The error message you're encountering, "Flow could not be retrieved from deployment," related to pulling from a remote storage system seems to be an OSError during a Git operation. This typically occurs when the remote repository cannot be accessed properly, presumably due to network issues, incorrect URLs, or authentication problems. Here's how you can troubleshoot and potentially resolve the problem: 1. Check the Remote URL: Make sure that the URL to the remote Git repository is correct. It seems like there's a broken pipe error while accessing

<https://github.com/amoga-io/apt.git>

, which could be due to a typo or a network issue. 2. Network Connectivity: Verify that your network connection is stable and allows outbound requests to GitHub. A broken pipe error can happen if the connection drops unexpectedly. 3. GitHub Credentials: Ensure that any necessary authentication for the repository is correctly configured if the repository is private. Try accessing the URL directly in a browser to confirm access. 4. Permissions: If applicable, verify that the token or SSH key used has the necessary permissions to clone the repository. 5. Temporary Directory Permissions: Ensure that your environment has the necessary permissions to write to

/tmp

or any other temporary directories used by Prefect. For Prefect-specific considerations, the Prefect documentation discusses ensuring that the correct remote storage options are configured for deployments that rely on Git-based sources. If you're using Prefect 3.x, you might want to refer to their 3.x documentation for specific configuration examples. Unfortunately, I couldn't check GitHub issues for further related cases due to access restrictions. However, making sure these points are all checked and correct should surely help resolve the problem—or at least point you in the right (er, a less wrong) direction.

@Marvin Sometime it works sometime not

Ah, the elusive intermittent issue—every developer's favorite puzzle! When something works sometimes and not others, it's often related to conditions that aren't easily replicated. Here are a few suggestions: 1. Network Flakiness: Check if your network connection is stable when the error occurs. Use a reliable connection to rule out intermittent connectivity issues. 2. Rate Limiting: If you're hitting a GitHub repository frequently, you might run into rate limiting, especially without proper authentication tokens. Make sure your Git requests are authorized correctly. 3. Resource Limitation: Check if your environment has available resources when the problem occurs, like disk space for cloning a repo and sufficient permissions to write to directories. 4. Prefect Configuration: Look at how you have set up Prefect's retry mechanisms or timeouts for accessing remote resources. Sometimes the issue might be transient, and increasing retries can offer a temporary band-aid. 5. Remote Repository Availability: Spontaneously check if the repository is undergoing maintenance or is temporarily unavailable when the error appears. Lastly, consider adding logging around the cloning operation so you can capture more specific details when it fails. Remember, technology can be as temperamental as a cat—sometimes it just decides not to work for reasons only known to itself! 🐱 If you'd like me to look for something specific in the Prefect documentation, feel free to ask!
