So I’m blind and love using Flash 3.1 TTS in AI Studio for fun little scenes and stories, but it’s literally not been able to run any prompt I give it and displays an “error at level 504” or something like that.

Please tell me the steps to reproduce a problem, that way; I can help you get this problem resolved.
