Trying to submit model access request in AWS Bedrock. I am getting "Operation not allowed" error on all models.

Hello.

Is it possible to enable it for other models rather than "Claude 3 Sonnet"?
If other models can be enabled, I think this is an issue on AWS or Anthropic's side.
I have seen similar events in the past.
Claude may not be available in some countries, or there may be restrictions imposed by AWS, so I recommend that you open a case with AWS Support under "Account and billing".
Inquiries under "Account and billing" are free of charge.

You can contact us by opening the AWS Support Console from the URL below.

Also, as shown in the answer to the question below, if your AWS account has just been created, requests may be restricted.
If you have just created an AWS account, you may want to create an EC2 instance and verify the account as shown in the answer to the question below.
