My app returns a 405 error code when I submit a form or call an API. Is this usually a method mismatch (GET vs POST) or server config issue, and how can I debug it (check allowed methods, server routing, CORS and rewrite rules)?
A 405 error is to indicate that the method of the HTTP protocol (such as POST or GET) is not permitted on that URL. Fix It Have your server or API configuration allow the correct method or your route handlers to accept the message method they are being sent.
