HTTP 414 URI Too Long is a client error-class status code defined in RFC9110. The request URI is longer than the server is willing to interpret.
Client-error responses signal that the problem is on the requesting side: the request is malformed, unauthorized, or aimed at something that isn't there. On the wire, the response begins with the status line HTTP/1.1 414 URI Too Long.
