Redshift serverless opt-in error

The error message "AWS Access Key ID needs a subscription for this service" corresponds to the OptInRequired error (HTTP Status Code: 403) that occurs when using Amazon Redshift Serverless.

This error typically indicates that your AWS account needs to explicitly subscribe to or opt-in for the Amazon Redshift Serverless service in the eu-west-2 region. Even though you have AdministratorAccess and Redshift permissions, some AWS services require an explicit opt-in process before they can be used in specific regions.

To resolve this issue, you should:

1. Verify that Amazon Redshift Serverless is available in the eu-west-2 region for your account
2. Check if there are any account-level restrictions or limitations
3. Contact AWS Support through your basic support plan to request access to the service in that region
4. Alternatively, try using a different region where the service might already be available for your account

Having payment methods and contact information set up is necessary but may not be sufficient if the service requires explicit subscription or if it's not yet fully available in your chosen region.

Hello.

You may need to sign in as the root user of your AWS account to complete the subscription, as described in the following documentation:

As mentioned in the AI response from AWS re:Post Agent, this error seems to be related to an issue with your AWS account, so I recommend opening a support case with AWS under “Account and billing” to inquire about it.
"Account and billing" inquiries are free of charge.
