Create Character - Generate with AI (Error)

Currently creating a character, has filled in the rest of the blanks section.

I usually use "Generate with AI" option to make it generate an image for the character.

It used to work before. Perhaps there's an error. Since no matter how many times I generate it, it will give a yellow pop out notification.

(Yes, I has filled out the name, appearance, pronouns, race, and class)
