Branch tip is behind remote

[kevinkace]

I have an action to build some frontend files (webpack/gulp/less), and commit them back to the repo.

The push is failing:

Run ad-m/github-push-action@master
  with:
    github_token: ***
    branch: origin HEAD

  env:

There is a git status command just prior to trying the push which shows the repo is up-to-date:

Run git status
  git status
  shell: /bin/bash -e {0}
On branch dm-action
Your branch is ahead of 'origin/dm-action' by 1 commit.
  (use "git push" to publish your local commits)

nothing to commit, working tree clean

My Build yaml:

I'm having the same issue, and would be interested in a fix as well!

Same issue here

Your branch is ahead of 'origin/dm-action' by 1 commit.

I believe It seems to me that the information presented is not current. You would have to do "git fetch" before "git status" to get current information.

Git pull solved it to me.

I had the same issue today and in my case it was because I was missing the branch portion (E.g. branch: ${{ github.ref }}).

After adding it to my workflow file the issue was resolved:

    - name: Push changes
      uses: ad-m/github-push-action@master
      with:
        github_token: ${{ secrets.GITHUB_TOKEN }}
        branch: ${{ github.ref }}

I'm curious about whether changing branch: 'origin HEAD' to branch: ${{ github.ref }} will do the trick in your case. I imagine it should, since it looks like you're trying to push to the same branch that triggered the action and github.ref will resolve to the current branch reference.

Same issue. Is this solved?
