Summary

Hi All,

When using --affected in Gitlab, I receive warning that it is unable to resolve the branch like below:
WARNING unable to detect git range, assuming all files have changed: Unable to resolve base branch. Please set with TURBO_SCM_BASE.

I followed the below recommendations but receive a different error: #9320 (comment)

Unable to query SCM: Git error: usage: git diff-tree

I have set the GIT_DEPTH: 0 on the pipeline stage but that doesn't seem to make a difference.
