The following applies to lines 12, 24, 35:

The error code 400 indicates that the request from the client was malformed or incorrect in some way. If the error was not caused by a bad request, then a different response code may be more appropriate (404 is often a good choice for GET requests, and 422 or 409 may be a good choice for POST requests).
