I use HTTP 422 to signal that a form was submitted with bad data,
which i believe is the correct status code: “indicates that the server
understands the content type of the request content […], and the syntax
of the request content is correct, but it was unable to process the
contained instructions.”[0]
htmx, however, treats all 4xx status codes as error and, by default,
does not swap the target with the response’s content. Until i found out
that i could change that behaviour, i worked around this limitation by
returning HTTP 200 for htmx requests, but it is a waste of time given
that htmx _can_ accept HTTP 422 as a non-error.
