Hi. I've been using this workflow successfully for a few months and it's suddently stopped working.
I see errors like this:

Checking the base repository state
  /usr/bin/git symbolic-ref HEAD --short
  main
  Working base is branch 'main'
  /usr/bin/git remote prune origin
  remote: Duplicate header: "Authorization"
  fatal: unable to access 'https://github.com/EnergySystemsModellingLab/MUSE2/': The requested URL returned error: 400

I've got all the "repo" scopes set for the token and it used to work fine. Not sure what has happened 😞. I generated a new token for the hell of it, but that didn't fix things. Maybe GitHub have changed something on their end?

Just thought I'd see if you had any ideas @a-kenji.
