@Marvin why prefect worker is saying None in this case: "Downloading flow code from storage at None"

The message "Downloading flow code from storage at None" typically indicates that there is an issue with how the flow code's storage location is configured or not configured properly. When a flow is executed, Prefect's execution environment needs access to the flow code, which is not stored in Prefect Server or Prefect Cloud by default. For the flow run, you need to specify where your flow code is stored. A common reason you might see "None" as the storage location could be due to one of the following scenarios: 1. The storage location was not correctly specified during the deployment process. 2. There could be an issue with the configuration file (possibly

prefect.yaml

) where the storage information is incomplete or incorrect. To resolve this, confirm that you've specified the flow code storage correctly, either through the CLI during deployment or within your Python code. The storage options can be specified via Prefect's interactive CLI, or in the deployment configuration file (

prefect.yaml

) if you used it for deployment. You should review the storage setup steps as outlined in the storage guide and the storage concepts documentation. Ensure your configuration aligns with the recommended methods for your deployment strategy. If the issue persists, it may be beneficial to check for similar problems reported on GitHub or discuss with members of the Prefect community for version-specific advice or known issues.

@Marvin i think that the storage is properly explained: • in the blocks i have "user-model" s3 block • in the code i have storage=S3.load(BLOCK_NAME_PREFECT_S3)

The error message you're experiencing does not directly correspond to the issues found in the GitHub search. However, it's possible that you're encountering a unique situation that hasn't been widely reported or may be due to a misconfiguration that's not immediately apparent in the search results. Since "Downloading flow code from storage at None" implies an issue with retrieving the flow code, and you've mentioned that you're using an S3 storage block with

storage=S3.load(BLOCK_NAME_PREFECT_S3)

, there could be several reasons why Prefect can't locate or access the flow code: 1. The block name (

BLOCK_NAME_PREFECT_S3

) you are using to load the S3 storage may be incorrect or not properly configured in Prefect Cloud or your local Prefect instance. 2. There could be a permissions issue with the AWS credentials that prevent the worker from accessing the S3 bucket. 3. The flow code may not have been uploaded correctly to the specified S3 bucket/path. Here are some steps you can take to help troubleshoot the issue: 1. Verify that the S3 block with the name you're using (

BLOCK_NAME_PREFECT_S3

) exists and is properly configured in Prefect Cloud or in your Prefect configuration. 2. Check that the AWS credentials being used have the necessary permissions to access the specified S3 bucket and read the flow code files. 3. Ensure that when you registered the flow, you specified the correct block for storage and that the flow code was uploaded successfully to S3. 4. If possible, check the logs for your Prefect agent or worker for more detailed error messages that may indicate the cause of the problem. If after these steps the issue remains unresolved, you might want to consider reaching out to Prefect support or the Prefect Community Slack for more personalized assistance, possibly providing them with additional context and configuration details for better guidance.
