I squashed a bunch of commits from my PR into one, and now the action is giving me a message:

##[error]The head commit for this pull_request event is not ahead of the base commit. Please submit an issue on this action's GitHub repo.
All: [".github/workflows/black.yml"]
Added: [".github/workflows/black.yml"]
Modified: []
Removed: []
Renamed: []
Added or modified: [".github/workflows/black.yml"]

The issue is that the base commit as such no longer exists because it was squashed. However, it appears that the changed files list is still correct. Does this error need to be raised? what needs to happen to handle squashed base/head commits?
