htmx:response:error
Fires for HTTP status 400 or higher
The htmx:response:error event fires when the server responds with an HTTP error status code (400 or higher).
When It Fires
After htmx:after:request and before the swap phase, when response.status >= 400.
This event does not fire for network errors or timeouts — use htmx:error for those.
