I have tried to use git clone as well as download a zip file from inside a GitHub action, and bot silently fail with an exit code 1. Is that a known bug or a feature? It might happen only if we're using the Windows-latest environment, for instance here (which is simply trying to download a raw file from a repository)
This is the debug output:
