I created a new repository, and named the master branch main. Running the lint command failed with a weird error message:

Error: Error running process: exit status 128
Removing ct container...
Done!

I took me a while to figure out that the linter requires a default branch named master. I know it is possible to re-configure using:

target-branch: main

However, I think that:

• There should be a proper warning: Branch "master" not found
• There should be some prominent piece of documentation
