Current behavior

There are a few places where error handling leaves abit to be desired. For example:

pizza/pkg/server/server.go

Lines 177 to 180 in f0071a5

	ref, err := gitRepo.Head()
	if err != nil {
	return err
	}

Suggested solution

Overall, we should be using tiered / structured logging so we always know where an error may have occurred. We should back-fill areas that may be missing this
