I am Jorah’s coworker. I do see a 404 error in the Developer Console. After leaving the console I also am presented a 404 error on the screen. I think it imperceptibly flashes briefly on the screen and then gets stuck behind the gear turning visual of DFFS opening and since it is not closed does not allow me to X out of the form opening. Only after closing the Developer Console is the error visible. I attached screen captures of both error messages. I also attached the JSON export of my form.
