Body

I get error trying to creare a PR wit copilot coding agent.
It'a aprivate repo, and I can create branches from my local without problems, there's not rules that clock the agents or branch actions.
I've tried 2 times asking to coding agent to open a request (using 2 premium) but it's getting error and there's not file changes.

The message error is :

Copilot stopped work on behalf of fdambrosio due to an error [1 hour ago]
[Copilot encountered a repository rule or branch protection rule violation when trying to push changes. See logs for details. If the problem persists, please contact GitHub Support. To retry, leave a comment on this pull request asking Copilot to try again.]

The new branch was created from the agent.

The log git error is the following:

$ git rev-parse --abbrev-ref HEAD HEAD
fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree. Use '--' to separate paths from revisions, like this: 'git [...] -- [...]'
<exited with exit code 128>

Call to command
$ git checkout REDACTED error: pathspec 'copilot/create-documentazione-tecnica-e-marketing' did not match any file(s) known to git
<exited with exit code 1>

I need support, thanks,
regards,
Francesco

Hey friend, I just hit this issue and adding permissions to read the repo to my agent file did the trick,

name: Copilot Setup Steps

jobs:
  copilot-setup-steps:
    runs-on: ubuntu-latest
    permissions:
      contents: read
    steps:
      - uses: actions/checkout@v4

[fdambrosio]

Thanks @truggeri ! Where I have to add this permissions? Which files and location?

[truggeri]

In my case, I have it in this file .github/workflows/copilot-setup-steps.yml which is a special file used to setup copilot.

thank you @truggeri it works!
