Description
Referencing the comments in #2820, and assuming that the return type is actually wrong, I think it should be awating the
PullRequest.Createso that it gets awaited inside the retry machinery?Still a draft, as if it's a correct cfhange it needs release notes (and It'd be a breaking change to the public API)
