[BUG] Error: Unable to locate the previous sha: fatal: ambiguous argument 'main': unknown revision or path not in the working tree

Is there an existing issue for this?

• I have searched the existing issues

Does this issue exist in the latest version?

• I'm using the latest release

Describe the bug?

Since today I'm getting the following error:

Use '--' to separate paths from revisions, like this:
'git [...] -- [...]'
Error: Unable to locate the previous sha: fatal: ambiguous argument 'main': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git [...] -- [...]'
Error: Please verify that the previous sha commit is valid, and increase the fetch_depth to a number higher than 40.
Error: Process completed with exit code 1.

I have tried setting the fetch-depth to 42 (higher than 40), with the same results.

I guess it has something to do with version 34.5.1 released yesterday.

To Reproduce

Run changed-files with the latest version.

What OS are you seeing the problem on?

ubuntu-latest or ubuntu-20.04

Expected behavior?

I would expect it not to fail.

@valberg This should resolved in the latest release.

I think this bug has recurred - potentially as a result of a git pull origin main on the target branch:
