Cannot trigger workflows manually targetting a copilot agent branch

[jwoodrow]

Describe the bug
When attempting to trigger a workflow manually using workflow_dispatch and attempting to target a specific branch, copilot branches are always missing in the list.

To Reproduce
Steps to reproduce the behavior:

1. Give Github Copilot agent a task on a repo with a workflow_dispatch workflow file
2. Attempt to run the workflow/action manually targetting the copilot branch
3. No results

Expected behavior
I should be able to run actions manually targetting a copilot branch, just like I can approve running automatic workflows on their branches/PRs

Runner Version and Platform

Don't think this is runner specific, I couldn't find a "Github Web interface for Github Actions" repo honestly.

What's not working?

No error, just the branches are not targetable

Job Log Output

No log output, because job cannot be run

Runner and Worker's Diagnostic Logs

N/A

I ran into this as well. In my case I was the one who delegated an issue to copilot and when it finished I could not run the workflow on this branch manually myself. My teammates on the other hand could see this branch in the dropdown list and trigger the workflow without problem. We all have same permissions in this repository.

I am encountering the same issue. The interim fix is to create a new branch and merge the copilots branch into it.
