Hi again @pepco as I explained in my answer below, the issue is probably caused by using source: GIT / git_source together with DABs. DBKS does not recommend this pattern for bundles, because the job runs from Git at runtime instead of from the workspace files deployed by the bundle.

In a mono repo, this can make relative imports like lib unreliable. You should remove git_source and source: GIT, deploy the code with the bundle, use workspace source paths, and include shared folders through sync.paths. Also don't forget to make the repo root explicit in sys.path or package the shared code as a wheel.
