Hi @szymon_dybczak,

Thanks for you reply. The issue is related to the fact if am also providing git_source parameters in this job (even though the source parameter of my task is set to WORKSPACE). When I comment the git_source part, specifying the path in a relative way works: python_file: ./../src/get_git_credentials.py

On this page I found this: "The job git_source field and task source field set to GIT are not recommended for bundles, because local relative paths may not point to the same content in the Git repository. Bundles expect that a deployed job has the same files as the local copy from where it was deployed." 

Instead, clone the repository locally and set up your bundle project within this repository, so that the source for tasks are the workspace."

I would like to configure this git_source parameters only for the task that requires it but it seems like it can only be defined at job level.
