The workflow fails when creating a pull request from a fork repository to an upstream repository.
Perhaps the error occurs because the correct branch name is now used in #70, and the branch cannot be found in the upstream repository where the workflow is to be executed.

The workflows where this problem has actually occurred following:
https://github.com/jaoafa/jaoweb4/blob/847e0875f9ae88cd69125433cfbfedfd9c33d753/.github/workflows/publish.yml#L98

The actual problematic workflows resulted in the following:

For pull requests from forks, it is preferable to use SHA. Alternatively, it would be possible to change this in inputs.
