Issue: Error when using safe_output.push_to_pull_request_branch

[TiggySravan]

I’m encountering an error whenever I try to use safe_output.push_to_pull_request_branch:

push_to_pull_request_branch
  └ {"result":"error","error":"Cannot generate incremental patch: failed to fetch..."}

I’m not sure whether this is a bug or if I’m missing some configuration. Could you please take a look?

Steps to Reproduce

Set up a workflow that is automatically triggered on CI when a pull request is opened or synchronized against the default branch (e.g., main), with path filters applied.

Configure the workflow similar to the following:

safe-outputs:
  github-app:
    app-id: ${{ vars.APP_ID }}
    private-key: ${{ secrets.APP_PRIVATE_KEY }}
  push-to-pull-request-branch:
    max: 3

Define and run the Agentic Workflow that attempts to push changes back to the pull request branch.

Observed Behavior

The workflow fails with:

Cannot generate incremental patch: failed to fetch...
Expected Behavior

The action should successfully generate and push incremental changes to the pull request branch.

Open your favorite agent cli, load our agentic-workflows agent and ask it to debug the workflow run url

Thanks! That's the first thing i did, when i had this issue. Have got not much out of that from debugging workflow runs!
