Head commit is not ahead of the base commit

[Spiroman]

Getting the following error for some of my CI's:
The head commit for this push event is not ahead of the base commit. Please submit an issue on this action's GitHub repo.
It is getting a base commit sha which I cannot find in the git log (presumably not there at all).
This behavior is not consistent, so I couldn't give you more info.

It does still correctly identify what files were changed since the last commit.

I am seeing this issue as well. The only additional info I have is that the error occurred while creating a Draft Pull-request

[dane-stevens]

Some additional info: This error occured when submitting a pull-request from a feature branch when the feature branch was behind master.

Seeing this issue too. Any ideas on a solution?

[dane-stevens]

@leslitagordita the issue resolved after pulling the latest master changes into my feature branch.

Is there any way to inform the user that a rebase might fix it?

[cristianmtr]

Would it be possible to automatically merge with master when checking files, and then get the list of changed files? We are constantly getting errors about this, when the master has had other commits in the meantime before merging the PR.

Or could you point out where in the code this could be change/added?

Saw this issue on my project as well. Since it still can generate the correct files, I just let the step continue:

- uses: jitterbit/get-changed-files@v1
  id: get-changed-files
  continue-on-error: true

I have cherry-picked 54f3703 (which fixes this issue) and released it in Ana06/get-changed-files@v1.2. I hope this change makes it upstream. In case it doesn't (or until it does), feel free to use Ana06/get-changed-files@v1.2 (which also supports pull_request_target and allow to filter files using regular expressions).

Btw, this is a duplicate of #11.
