I'm a Git novice and am testing some Git tool scripts via BATS (Bash Automated Testing System).
I'm getting the following error:
fatal: Not a valid object name HEAD
The test does the following setup before running the tooling script:
git remote add origin my_repo/.git # Create repository
git switch --create main # Create main branch
git commit --allow-empty -m "Initial commit" # Initial commit on main
git tag v11.0.0 # Create a tag on main
git switch --create release/12.0.0 # Create release branch
git commit --allow-empty -m "Commit for v12.0.0" # Initial commit on release branch
git merge tags/v11.0.0 # Merge tag onto the release branch
git switch main # Switch back to main
git commit --allow-empty -m "Subsequent commit" # Another commit on main
git config --add receive.denyCurrentBranch ignore # Allow direct pushes to the checked-out branch
The test then runs the tooling script, which tries to get the latest tag in the main branch:
LATEST_TAG=$(git describe --tags $(git rev-list --tags --max-count=1))
... which is where the error ("fatal: Not a valid object name HEAD") occurs.
Would anyone be able to advise what the issue is, please?
Not shown in the question above, but the problem was to do with how I invoked Git in the following command (specifically, the "git rev-list" part):
LATEST_TAG=$(git describe --tags $(git rev-list --tags --max-count=1))
Once I had fixed this, the BATS test worked correctly.
