Hello 👋 I am setting up

prefect.yaml

deployments and have 2 types of pull actions I am assigning to YAML aliases (dev/prod). This is the error I get at runtime:

Flow could not be retrieved from deployment.
Traceback (most recent call last):
  File "/usr/local/lib/python3.10/site-packages/prefect/deployments/steps/core.py", line 154, in run_steps
    step_output = await run_step(step, upstream_outputs)
  File "/usr/local/lib/python3.10/site-packages/prefect/deployments/steps/core.py", line 110, in run_step
    raise ValueError(
ValueError: Step has unexpected additional keys: repository, access_token, prefect.deployments.steps.git_clone

Here is my

prefect.yaml

, am I misusing aliases here?

name: my-prefect
prefect-version: 2.14.9

actions:
  pull: 
    dev: &pull_dev
      - prefect.deployments.steps.git_clone:
        repository: <https://github.com/my-repo.git>
        branch: dev
        access_token: "{{ prefect.blocks.secret.my-secret }}"
    prod: &pull_prod
      - prefect.deployments.steps.git_clone:
        repository: <https://github.com/my-repo.git>
        branch: main
        access_token: "{{ prefect.blocks.secret.my-secret }}"

build: null
push: null
pull: null

# the deployments section allows you to provide configuration for deploying flows
deployments:
- name: my-deploy
  version: 1
  tags: []
  description: 
  schedule:
  entrypoint: 
  parameters: {}
  work_pool:
    name:
    work_queue_name: 
    job_variables: {}
  pull: *pull_dev  # I want this deployment to pull from the dev branch

I am able to successfully run the deployment with a single

pull:

definition, but it breaks when trying to use an alias to define the pull action on the deployment pull:

*pull_dev

hey @Sean Malone what happens if you remove that pull key that you have inside of your actions object? i suspect that’s why it can’t find the expected keys, bc that pull key / layer shouldn’t be there i.e. you can use whatever type of actions in build / push / pull steps, so you shouldn’t have to distinguish them in your action definitions

@Nate I tried removing the pull key

actions:
  dev: &pull_dev
    - prefect.deployments.steps.git_clone:
      repository: <https://github.com/my-repo.git>
      branch: dev
      access_token: "{{ prefect.blocks.secret.my-secret }}"
  prod: &pull_prod
    - prefect.deployments.steps.git_clone:
      repository: <https://github.com/my-repo.git>
      branch: main
      access_token: "{{ prefect.blocks.secret.my-secret }}"

But am am still getting the “unexpected keys” error

maybe its an indenting issue? this works for me fine

definitions:
  actions:
    dev_clone: &dev_clone
    - prefect.deployments.steps.git_clone:
        repository: <https://github.com/zzstoatzz/prefect-monorepo>
        branch: dev

deployments:

  work_pool:
    name: local
  pull: *dev_clone

Yep! That was very helpful, and i’ve identified the issue. Basically it was just incorrect indentation after the

prefect.deployments.steps.git_clone:

block. I had 2 spaces of indentation, and after increasing it to 4 it ran successfully. Fixed actions block:

actions:
  dev: &pull_dev
    - prefect.deployments.steps.git_clone:
        repository: <https://github.com/my-repo.git>
        branch: dev
        access_token: "{{ prefect.blocks.secret.my-secret }}"
  prod: &pull_prod
    - prefect.deployments.steps.git_clone:
        repository: <https://github.com/my-repo.git>
        branch: main
        access_token: "{{ prefect.blocks.secret.my-secret }}"

Thanks @Nate!
