I encountered the same issue. When I opened the developer mode in the browser, I noticed that before sending a request, an error about a missing use case form popped up, which triggered an "operation not allowed" error. However, when applying for models other than Claude, there's nowhere to fill in a use case. I think this is a bug in the AWS system.
