@Marvin Do you have a video how do deploy with private repository from github?
m
To deploy a Prefect flow from a private GitHub repository, you'll need to authenticate your environment to access the repository. Here's a concise guide based on the Prefect documentation: 1. Authentication: - Use a Personal Access Token (PAT) from GitHub to authenticate. It's recommended to use HTTPS with fine-grained PATs to limit access to specific repositories. You can create a PAT under GitHub's Developer Settings. 2. Configuration: - Store your credentials securely using a Secret block or a credentials block specific to your version control platform within Prefect. - Reference this block in your deployment code. 3. Deployment: - If using Prefect's Python deploy method, provide a 
GitRepository
object instead of a URL for the private repository. For more detailed information, you can visit the Prefect documentation on storing flow code. If you're looking for a video, I recommend checking Prefect's official YouTube channel or searching for community tutorials on platforms like YouTube.

@Marvin I add the name block on yaml but I got the error Encountered error while running prefect.deployments.steps.git_clone
m
The error you're encountering with 
prefect.deployments.steps.git_clone
might be related to the configuration of the 
prefect.yaml
file, especially regarding the block name or credentials. Here are some steps to troubleshoot and resolve the issue: 1. Check Block Configuration: - Ensure that the block name specified in your 
prefect.yaml
file matches exactly with the block you have created in the Prefect UI or through code. The block should store your GitHub credentials securely. 2. Verify Credentials: - Make sure that the credentials (like a Personal Access Token) are correctly configured and have the necessary permissions to access the private repository. 3. YAML Syntax: - Double-check the syntax of your 
prefect.yaml
file. YAML is sensitive to indentation and formatting. 4. Access Token: - If using a Secret block, ensure it is correctly referenced in the 
prefect.yaml
. You may also directly provide a token to an 
access_token
field if applicable. 5. Documentation Reference: - For more detailed instructions on configuring blocks and handling credentials, refer to the Prefect documentation on YAML configuration. If these steps don't resolve the issue, you might want to check the Prefect community forums or GitHub issues for similar problems and solutions.

@Jake Kaplan I need help here 😄, where am I making a mistake? I got an error related to git_clone (I guess). prefect.yaml
Copy code
pull:
  - prefect.deployments.steps.git_clone:
      repository: git@github.com:X
      branch: main
      access_token: "{{ prefect.blocks.secret.credential-git-prefect }}"
j
Can you try changing the pull step to look like this? 
access_token: "{{ prefect.blocks.github-credentials.credential-git-prefect }}"
or this 
credentials: "{{ prefect.blocks.github-credentials.credential-git-prefect }}"
the 
secret
part indicates a 
Secret
block type, but you're using a 
GitHubCredentials
block type
sorry typo, I fixed it now

      branch: main
      access_token: "{{ prefect.blocks.github-credentials.credential-git-prefect }}"
What I'm doing wrong?
m
The error you're encountering with the 
git_clone
step might be due to how the 
access_token
is referenced in your 
prefect.yaml
. Here are a few things to check and correct: 1. Block Reference: - Ensure that the block name 
github-credentials
and the specific credential 
credential-git-prefect
are correctly set up in Prefect. The reference should match the block's exact name and structure. 2. Access Token Format: - The 
access_token
should be properly referenced using the correct block and variable syntax. Verify that 
github-credentials
is a valid block type in Prefect and that it contains the 
credential-git-prefect
. 3. YAML Syntax: - Double-check the YAML syntax for any indentation or formatting issues. YAML is sensitive to these details. 4. Access Method: - The access method should be consistent with Prefect's guidance for accessing secrets and credentials at runtime, as unresolved references are pulled during deployment execution. For more details, you can refer to the Prefect YAML configuration documentation. Make sure to verify the block's existence and its configuration in the Prefect UI or through the Prefect Python API.

@Marvin When the prefect.yaml is modified and saved, I just need to deploy and run the flow or I need to push the code to repository?
m
When you modify and save the 
prefect.yaml
file, you'll typically need to follow these steps: 1. Deploy the Flow: - Use the Prefect CLI or API to deploy the flow. This step updates the deployment configuration with any changes made in the 
prefect.yaml
file. 2. Push to Repository: - If your deployment process relies on the code being up-to-date in the repository (e.g., if the flow code is pulled from the repository during deployment), you should push your changes to the repository. This ensures that the latest code, including the updated 
prefect.yaml
, is available for the deployment. 3. Run the Flow: - Once deployed, you can run the flow using the Prefect CLI, UI, or API. In summary, if your deployment setup requires the repository to have the latest code, you'll need to push the changes. Otherwise, deploying and running the flow with the updated 
prefect.yaml
should suffice.

@Marvin, I got an error when a flow is running. "Failed due to a(n) 
ValueError
in loading the flow. The error is caused by unexpected additional keys in a step, specifically 'repository', 'access_token', and 'prefect.deployments.steps.git_clone'." What is the way to fix this error?
m
The error you're encountering is due to unexpected keys in the 
prefect.yaml
file. Here's how to address this issue: 1. Correct Key Usage: - Ensure that the keys you're using in the 
prefect.yaml
file are supported and correctly placed. The 
git_clone
step should only contain keys that are recognized by Prefect for that specific step. 2. Review the 
git_clone
Step: - The 
git_clone
step should be configured correctly. According to the documentation, the 
repository
and 
access_token
should be part of a correctly structured step. Ensure you're using the correct syntax and structure. 3. Example Structure: - Here's an example of how the 
git_clone
step should be structured in the 
prefect.yaml
file:
Copy code
yaml
     pull:
       - prefect.deployments.steps.git_clone:
           - repository: "git@github.com:adrianoresende/prefect.git"
           - branch: "main"
           - access_token: "{{ prefect.blocks.github-credentials.credential-git-prefect }}"
4. Remove Unnecessary Keys: - If 
prefect.deployments.steps.git_clone
is incorrectly placed or if there are additional keys that are not supported, remove or correct them. 5. Documentation Reference: - For more detailed information on YAML configuration and supported keys, refer to the Prefect YAML documentation. By ensuring the 
prefect.yaml
file is structured correctly with only supported keys, you should be able to resolve the error.

@Marvin I got another error: "Failed due to a(n) 
ValueError
Step has unexpected additional keys: access_token, prefect.deployments.steps.git_clone. This error occurred while trying to load a Prefect flow." What it means?
m
The error you're encountering indicates that the 
prefect.yaml
file contains keys in the 
git_clone
step that are not recognized or expected by Prefect. Specifically, it mentions 
access_token
and 
prefect.deployments.steps.git_clone
as unexpected keys. Here's how you can address this issue: 1. Check Step Configuration: - Ensure that the 
git_clone
step is configured with only the expected keys. Typically, this step should include parameters like 
repository
, 
branch
, and possibly a credentials reference. 2. Remove Incorrect Keys: - The 
prefect.deployments.steps.git_clone
should not be used as a key itself. Instead, it should be a part of the step definition. Make sure it's structured properly under the 
pull
section. 3. Example Configuration: - Here's an example of how the 
git_clone
step should be structured:
Copy code
yaml
     pull:
       - prefect.deployments.steps.git_clone:
           repository: "git@github.com:adrianoresende/prefect.git"
           branch: "main"
           credentials: "{{ prefect.blocks.github-credentials.credential-git-prefect }}"
- Note that the 
credentials
key should be used instead of 
access_token
if you're referencing a block for authentication. 4. YAML Structure: - Ensure that your YAML file is correctly indented and structured. Misplaced keys or incorrect indentation can cause unexpected behavior. 5. Documentation Reference: - Refer to the Prefect YAML documentation for guidance on the correct structure and supported keys for deployment steps. By correcting the structure and ensuring only supported keys are used, you should be able to resolve the error.

The error you're experiencing is due to incorrect structure in the 
prefect.yaml
file, particularly with the 
git_clone
step. Here's how you can fix it: 1. Correct the 
git_clone
Step Structure: - The 
git_clone
step should be indented correctly under the 
pull
section, and it should only include supported keys. The 
access_token
should be referenced as 
credentials
if you're using a Prefect block for authentication. 2. Example Correction: - Here's a corrected version of your `prefect.yaml`:
Copy code
yaml
     name: Prefect
     prefect-version: 3.1.9

     build: null

     push: null

     pull:
       - prefect.deployments.steps.git_clone:
           repository: "<https://github.com/adrianoresende/prefect.git>"
           credentials: "{{ prefect.blocks.secret.token-prefect-repo-github }}"

     deployments:
       - name: test-name
         entrypoint: flows/test.py:test
         parameters:
           name: Zuzu
         work_pool:
           name: AI Project
         schedule: null
3. Key Changes: - Replace 
access_token
with 
credentials
to correctly reference the authentication block. - Ensure the indentation is consistent and correct, as YAML is sensitive to whitespace. 4. Documentation Reference: - For more details on configuring the 
prefect.yaml
, refer to the Prefect YAML documentation. By making these adjustments, your configuration should align with Prefect's expected structure and resolve the error.

The error you're encountering indicates that the 
git_clone
step in your 
prefect.yaml
file is not structured correctly. Specifically, the keys under 
prefect.deployments.steps.git_clone
are not being recognized as valid. Let's address this: 1. Indentation and Key Structure: - Ensure that the keys under 
prefect.deployments.steps.git_clone
are properly indented. The colon (
:
) after 
git_clone
should be followed by a new line and then the indented keys. 2. Corrected 
prefect.yaml
Structure: - Here's a corrected version of your `prefect.yaml`:
Copy code
yaml
     name: Prefect
     prefect-version: 3.1.9

     build: null

     push: null

     pull:
       - prefect.deployments.steps.git_clone:

         work_pool:
           name: AI Project
         schedule: null
3. Key Points: - Ensure that the 
repository
and 
credentials
keys are indented under 
git_clone
. - Verify that the block reference 
{{ prefect.blocks.secret.token-prefect-repo-github }}
is correctly set up in Prefect. 4. Documentation Reference: - For additional guidance, refer to the Prefect YAML documentation. By ensuring proper indentation and structure, the configuration should be valid and the error resolved.

@Marvin Now it is another error: Failed due to a(n) 
AttributeError
caused by a string object missing the 
items
attribute, likely originating from a Prefect flow run process. My file prefect.yaml:
Copy code
name: Prefect
prefect-version: 3.1.9

build: null

push: null

pull:
  - prefect.deployments.steps.git_clone:
      repository: "<https://github.com/adrianoresende/prefect.git>"
      credentials: "{{ prefect.blocks.secret.token-prefect-repo-github }}"

deployments:
  - name: test-name

    parameters:
      name: Zuzu
    work_pool:
      name: AI Project
    schedule: null
m
The 
AttributeError
you're encountering, indicating a string object missing the 
items
attribute, suggests there might be an issue with how the 
prefect.yaml
file is interpreted, possibly due to incorrect formatting or structure. Here's how to address the issue: 1. Remove Angle Brackets: - Ensure that the repository URL does not include angle brackets (
<
and 
>
), as these might be interpreted incorrectly. Use the plain URL string. 2. Corrected 
prefect.yaml
Structure: - Here's a revised version of your `prefect.yaml`:
Copy code
yaml
     name: Prefect
     prefect-version: 3.1.9

     build: null

     push: null

     pull:
       - prefect.deployments.steps.git_clone:
           repository: "<https://github.com/adrianoresende/prefect.git>"
           credentials: "{{ prefect.blocks.secret.token-prefect-repo-github }}"

     deployments:
       - name: test-name
         entrypoint: flows/test.py:test
         parameters:
           name: Zuzu
         work_pool:
           name: AI Project
         schedule: null
3. Ensure Proper Block Setup: - Verify that the block 
{{ prefect.blocks.secret.token-prefect-repo-github }}
is correctly configured in Prefect, and it returns the expected credential format. 4. Review the Flow Code: - Double-check the flow code specified in 
flows/test.py:test
to ensure it does not inadvertently return or handle strings in a way that would cause this error. 5. Documentation Reference: - For more details on configuring the 
prefect.yaml
, refer to the Prefect YAML documentation. By ensuring the structure is correct and removing unnecessary symbols, you should be able to resolve the error.

@Jake Kaplan I tried various ways and didn't find the error or possible bug. The documentation needs to explain better the difference between access_token and credentials when we use these words. 1. I run git clone on my terminal with token, and it is successful. 2. I tried with access_token and credentials with secret or github blocks, but I don't know what is the best way. The last error about missing the items is vague and without a solution in the message. What I'm doing wrong?
j
Sorry you're running into friction, definitely agree the docs can be better here. I also believe I gave you too vague an answer in another thread, which I apologize for. Lets see if we can get this deployment going... • 
access_token
is correct when you're passing a 
Secret
block or just passing the raw value • 
credentials
is correct if you're using a full credentials block like 
GitHubCredentials
So I would expect all 3 of these to work: • with token directly in your pull step
Copy code
pull:
- prefect.deployments.steps.git_clone:
    repository: <my repo>
    access_token: <raw github token>
• with a secret block that only contains the token
Copy code
pull:
- prefect.deployments.steps.git_clone:
    repository: <my repo>
    access_token: '{{ prefect.blocks.secret.my-gh-token }}'
• with a github credentials block
Copy code
pull:
- prefect.deployments.steps.git_clone:
    repository: <my repo>
    credentials: '{{ prefect.blocks.github-credentials.my-gh-creds }}'
