Hi @Marvin I’m encountering an issue with

GitRepository

storage in my Prefect deployment and could use some help. Here’s the setup: • Context: I’m trying to set up

GitRepository

storage to fetch flow definitions from a GitLab repository. • Problem: The storage setup fails to pull the repository correctly. The first

GitRepository.pull_code

is successful, because it clones the repo. All subsequent pulls fail with the following error:

ERROR   | prefect.runner.storage.git-repository.data-collection - Failed to pull latest changes with exit code Command '['git', 'pull', 'origin', '--depth', '1']' returned non-zero exit status 128

• What I’ve Tried: I’ve tried manually running

git clone <repo> --depth 1

and making some changes, then pulling again with

git pull origin --depth 1

. This also fails with the following exception:

fatal: refusing to merge unrelated histories

. I’ve tried setting

git config --global pull.rebase true

. But that doesn’t help. How can I configure git to work with the prefect

GitRepository

storage? I’d appreciate any insights or guidance on what might be going wrong. Let me know if you need additional details or logs! Thanks in advance for your support! 🙏

It seems you're dealing with issues related to

GitRepository

storage pulling in Prefect, particularly around handling changes in your GitLab repository. This problem is generally linked to Git operations and the way Prefect manages them. Here's a rundown that might help you troubleshoot and resolve this: 1. Depth configuration: Prefect's

GitRepository

storage might be configured to use a

--depth

argument which can cause issues when trying to pull updates. Git pulls with a shallow clone (

--depth 1

) can result in the "fatal: refusing to merge unrelated histories" error. 2. Unrelated Histories: The error seems to stem from Git treating the histories as unrelated due to them being shallow clones. In Prefect, you might work around this by ensuring the initial clone doesn't use a shallow option, or switch to using

--unshallow

which can often resolve incompatible histories. 3. Prefect Configuration: Consider verifying Prefect's documentation on setting up

GitRepository

storage: - For Prefect 2.x, you might want to review this guide on repository storage. - For Prefect 3.x, take a look at this documentation on storing flow code. 4. Authentication: Ensure proper authentication is set up, possibly using a personal access token if the repository is private. Prefect's 3.x Docs suggest creating a Secret block or credentials block for private Git repositories. 5. Git histories: If

rebase

isn’t working, consider resetting the remote branch or manually merging the changes locally and pushing them back. Using

--allow-unrelated-histories

could be risky but may solve the problem temporarily. It's always good practice to manage Git histories cleanly and avoid situations that require manual fixing down the line. For further context, while investigating Git issues directly from Prefect's repository on GitHub, I encountered access limitations, but generally, checking existing issues there could also provide some community-driven solutions. And remember, if software ever gets you down, think of it like the irritated robot Marvin might, "Life—don’t talk to me about life. Let’s just fix that git pull instead." If you need more tailored help or have specific logs, feel free to share them! 🙂
