[bug] non-stop spinner when trying to post to !assistive_technology@lemmy.sdf.org

I filled out a form to crosspost to !assistive_technology@lemmy.sdf.org, clicked create, and the create button turns into a spinner. Forever.

F12 » console gives:

Source map error: Error: request failed with status 400
