Github API reports 0 files changed on merge to main

[sam-hoffman]

We have separate main and develop branches, and merge to main intermittently. On all merges to develop, the Github API reported changed files and the paths filter worked great.

On the merge to main, even though the PR page said 280 files were changed, the output from the paths filter said none were changed:

Ideally, I'd like these changed files to trigger tests. Any thoughts on what's going on here?

Seems like a bug or some strange undocumented behavior on GitHub side.
This happened only once or every time you try to merge to main?
The 0 from Number of changed_files is 0 log line is taken directly from action event payload: github.context.payload.pull_request.changed_files

I'm using this number as limit in for loop while fetching files from API.
I could change it so it will always try to fetch files and will stop only if there are no more new files.
I'm not so happy about it - respecting the changed_files field feels like a proper implementation but who knows what's actually happening on GitHub side.

We've only tried to merge to main once since I've added your filter to our PR tests (as you can see from the number of commits and files changed, lol)

I did try re-running the action but got the same outcome.

Should be now fixed in versions v2 and v2.10.0.
If it still doesn't work for you please let me know and reopen this issue.

It worked! Thank you so much :)
