Treehouse TeacherThe update_signature method is expecting a string containing a number (like "1"), but instead it's getting a symbol. So the problem is actually in the put "/signatures/:index" route, where update_signature is called. You need to use the :index symbol to get a value from params hash, then pass that value to update_signature. But instead, the :index symbol is getting passed to update_signature directly.
