What happened:

$ ct list-changed
Error: Error running process: exit status 128
Error running process: exit status 128

What you expected to happen:

I expected it to work, or provide a useful error message.

How to reproduce it (as minimally and precisely as possible):

Create a new git repo that uses main instead of master as its default branch, and has no master branch.
Commit a helm chart into the main branch
Create a branch and modify the helm chart and then commit it to your branch.

Run:

$ ct list-changed
Error: Error running process: exit status 128
Error running process: exit status 128

Anything else we need to know:

A descriptive error message would be a big improvement, but it would also be nice if the tool actually used main as the default target branch, and if it gets an error finding that branch, it falls back to trying master before finally giving the user an error that "the default branch (main or master) can not be found. Please provide the correct target-branch with --target-branch"
