hi! i hope it's ok to comment but i'm having an issue generating a preview or code, a mobile preview, or the code itself. i'm getting this error:



and clicking 'details' gives the same message in a different pop up. i don't have all the info in that i want, just placeholder images and a few basics filled out, but i'm still getting the error. i really like this code tho i've been looking for something like this for a while!
