subprocess.CalledProcessError: Command '['git', 'cat-file', 'blob',

Root Cause (optional)

Git tag pytest-backend-1.2.1 exists and is the latest tag, but each subproject in this repo contains a separate individual file poetry.lock, hence the path is incorrect, but should be pytest-extension/poetry.lock in this case.

See function get_dependencies_from_latest_tag() in file exasol/toolbox/util/dependencies/poetry_dependencies.py.
