PR Creation fails

[thiagodebastos]

Problem

I cannot use the changeset Github action since it fails to create a PR, with the following error:

/usr/bin/git push origin HEAD:changeset-release/refs/pull/35/merge --force
To https://github.com/my-account/my-repo
 + 55fdd6e...d927a56 HEAD -> changeset-release/refs/pull/35/merge (forced update)
{
  "total_count": 0,
  "incomplete_results": false,
  "items": []
}
creating pull request
Error: HttpError: Validation Failed: {"resource":"PullRequest","field":"base","code":"invalid"}
Error: Validation Failed: {"resource":"PullRequest","field":"base","code":"invalid"}
HttpError: Validation Failed: {"resource":"PullRequest","field":"base","code":"invalid"}

I can see that the commit and branch are created. So that part works fine. I am unsure how to debug the rest.

I have tried setting baseBranch to master in .changeset/config.json but this does not help.

I have also tried setting all permissions to write in case the error message was incorrect.

Any pointers in the right direction would be great as I cannot seem to find any answers out there. I will report back if I find a solution.

This error would make sense if the action is attempting to create a PR from a fork, since that permission is disabled in our repo.

Update: I think this could be happening because I am testing the action from a branch to see if release and PR creation are working as intended, and the action then tries to create a PR from this branch, when it expects to be creating a PR from master? I'm a bit confused as to how to set this up to be honest.

[thiagodebastos]

I figured it out, the issue was that I didn't understand how this is all supposed to be set up and because I was testing the action in a PR to master, the error I got back about the base being invalid meant that it was looking to create a PR into master but was getting confused since it was being run from a PR into master already. Hopefully anyone who runs into this issue will find this and not be too lost in a rabbit hole!

@thiagodebastos thank you for this issue, I had exactly same issue and error isn't most descriptive thing I've seen :D. For me it breaks my whole flow it would be nice if changesets/action would allow passing ref of branch if it cannot pull data from pull_request
