NOTE! For XHR/Ajax or API requests, this action would normally respond with
204 No Content: an empty white screen. Since you'
re loading it in a web browser, we assume that you expected to actually
render a template, not nothing, so we're showing an e
rror to be extra-clear. If you expect 204 No Content, carry on. That's what
you'll get from an XHR or API request. Give it a
shot.):
