Empty commits on open PR

[nagano]

After opening a PR with the changes, if I run the action again it pushes an empty commit to the branch.
Is there any way to avoid this?

I have a workflow that runs a couple times a week and the PR can remain open for a while, and I'd like to avoid the noise.

Your first run creates a branch and opens a PR, the second run pushes an empty commit to the already created branch?

[nagano]

Correct. After the first run, it pushes a commit with no content on the next runs

The action would stop if the content would not change but in your case its not possible.

If you create branches for your changes, you could check in a step before if a branch already exists and stop if so.

git ls-remote --exit-code --heads origin <branch-name>

Is the problem related to creating a branch + pushing the changes?

In my case, there could be changes between the first run (create branch + open PR) and the next time it runs the action, since the YAML values are based on a separate config file. So I need to run the action every time to check for new changes, I can't stop the whole thing based on the existence of the branch.

Also, forgot to mention, but my workflow is targeting a different target repo

Hmm okay, I can check if I find a possible check to avoid it but not sure if I can do much against it.
