I don't see a repository under ingka-group-digital/resolutions. Is this regular GitHub (not enterprise) and you have write? I suspect there is a permissions / visibility issue somewhere.

[HasanKhatib]

ingka-group-digital is a private organisation on github. I will check our token permissions

I would sanity check a similar run against a public repository. I'm guessing the 404 error is correct in that the token you have in the GitHub action runner cannot "see" the repository. The thing to try after that would be using a PAT instead.
