Bash exited with code '128'.

(these scripts fail)

  - script: |
      git add --all .
      git commit -m 'Update website'
      git push origin master
    displayName: 'Git push master branch

  - script: |
      git add --all .
      git commit -m 'Update website'
      git push https://$(GitHubPAT)@github.com/coderdojo-linz/$(target_repository).github.io.git
    workingDirectory: $(Agent.BuildDirectory)/dest
    displayName: 'Git push preview to destination repo'```
