Git fallback not working properly

I run nx-containers using Buildbot as our CI.

The command npx nx affected --base=origin/development --head=<sha> --target=container --parallel=1 fails with the following error:

Unsupported CI Provider... Using Local Environment as fallback
[command]/usr/bin/git log -1 --pretty=format:%ae
me@mycompany.example[command]/usr/bin/git symbolic-ref HEAD
fatal: ref HEAD is not a symbolic ref
>  Removing temp folder /tmp/docker-build-push-aemX4D 
 NX   The process '/usr/bin/git' failed with exit code 128
Pass --verbose to see the stacktrace.

Detecting an unsupported CI is correct because ci-info does not recognize buildbot and ci-context cannot handle it. The fallback to Git tries to fetch the current SHA using Git.ref, but I wonder why the exception is not handled correctly and the fallback using git tag is used - which I assume because the last command printed is git symbolic-link HEAD followed by the error message.

The unit test do not cover this case, AFAICS. I tried to enhance them but my skills in TS are marginal at the moment.
