Not sure about you guys but I kept putting in the title of the example and not what they wanted me to put in. I kept putting “cat-photo-app” and not “cat-photo-form”.
Also, drop the addition of “form id=blahblahblah” and just put “id=blah” right after the action element but before the end arrow.
“form action=”/submit-cat-photo" id=“cat-photo-form” " Minus the outside quotes obviously.
