Fails in repos without a master branch

[echennells]

Newer github repos default branch is renamed main. I tried putting in a BRANCH variable but it didn't seem to pick it up.

I ran into this issue as well

I just added

          branch: main

into the with: section and it worked after

Indeed, we choose master as default. As everyone, I'm aware of the switch to main default branch name for new repos, but I wonder how many repos are out there still using master. It's a though decision to choose a default, and this is no different.
