No, my mom is not eidetic, and no, she's not going to upload a photo of her living room.
Totally agree with you, though, when the full error message is at least capable of being copied to the clipboard.
Could the manufacturer solve this in a better way? Probably but that won't solve the issue the customer has now.
Jokes aside, "upload a photo of her living room" was meant to highlight the ridiculousness of the UX. I believe the designer of that flow had an OKR to decrease the number of reported bugs.
