Motivation and Context
I noticed when running fastlane in a folder that was not a git repo, that things would fail. There are some actions that use
Actions.git_branch
a dynamic default value that would error out. This will add safety for when there is no git repo.Resolves #18467
Description
This solution wraps the shell command that
Actions.git_branch
executes in a begin/rescue and returnsnil
if an error is caught.
