How to handle POST request errors?

[bencroker]

When using hx-post I see in the console a POST request to the value, quickly followed by a GET request to the value, the result of which is returned. Is it possible to handle errors that are returned in the POST response? All I see in the console is a 302 Found status and an empty body, even though my controller is returning a 200 with a body. Any insights into how this works would be much appreciated.

If your server is returning an error code, htmx will trigger the responseError event (https://htmx.org/events/#responseError.htmx). But it sounds like that isn't what's happening here.

You can turn on logging in htmx to see everything that's going on: https://htmx.org/docs/#events. It can be a little overwhelming, but maybe that will illuminate things more.

hey ben, can you post the HTML for me to look at? I don't know why a GET should be issued immediately after a POST, that sounds suspicious.

Thanks @rschroll and @chg20, after further investivation it seems the server was returning a 302 status after all. Fixing the controller to return a 200 status code solved it. The responseError event looks perfect for future use, cheers!
