I've been searching Google and cannot find anything on this error.
Here is the full error:
git commit -m "update ui" INVALID COMMIT MSG: does not match "type scope: subject" ! was: "update ui" Note: scope must be only letters. You have a commit-msg hook on your system that is enforcing a format on your commit message. This is presumably company policy of some kind.
scope: message where scope must be only letters (I am guessing no digits or whitespace).
