Description

In #974 CI action, It tries to pull my branch in the main repo instead of the forked repo. See the logs.

I think the line in the GitHub action below only works when someone from the organization creates a pull request but not from someone outside the organization who has to fork the repo to create a PR.

Steps to Reproduce the Issue

Fork the repo. Create a PR and let the maintainer run the CI for first time contributors to this repo like me 😅.

Notes

I think we need to use github.ref or $GITHUB_REF to get the ref to the PR from forks. Other instances of happening this is in #678 (logs)
