A few days ago, I had the Image Update Automation working, it was creating a Merge Request on GitLab when a new version of my deployment was detected. After running a flux uninstall and flux bootstrap again, I'm getting this error in my automation:

failed to update source: failed to push to remote: authorization failed: You are not allowed to upload code.

Im bootstrapping flux using a token with a scope of API permissions like stated in the documentation.
Does anyone know where i should be looking to resolve this issue?

The FluxCD source controller has no issues syncing with the repository and deployment my helm release.
I have tried creating new access tokens with various scope levels and bootstrapping with them, but the error remains the same
