If an OPTIONS request is received, and if no function is defined, an automatic response will be generated, which includes an <code>Allow</code> header with all supported methods.

==Raise Errors==

If an error is raised during the evaluation of a RESTXQ function, an HTTP response with the status code 400 is generated. The response body contains the full error message and stack trace.
