INVALID PAYMENT INSTRUMENT error while trying to access bedrock claude models.

The INVALID_PAYMENT_INSTRUMENT error you're experiencing is related to an AWS Marketplace Agreement failure. This is a known issue that can occur when requesting model access in Amazon Bedrock, particularly for certain payment configurations.

Here are some steps to address this issue:

Common Causes:

• Invalid payment method configuration
• Restricted geo-location limitations
• Issues specific to certain account types and payment instruments

Recommended Actions:

1. Review Payment Method Requirements: Ensure your payment method meets all AWS Marketplace requirements. Some payment instruments may have restrictions depending on your account type and location.

2. Check Geo-location Restrictions: Verify that your location is not subject to restrictions that could prevent the marketplace agreement from being completed.

3. Update Your Support Case: Since you've already opened a support case, I recommend adding detailed correspondence through the AWS Support Center (https://console.aws.amazon.com/support/). Include specific details about:

• The exact error messages you're receiving
• All payment methods you've attempted
• Your account type and region

4. Review Support Plan Options: If you need faster response times for critical issues, consider reviewing your AWS Support plan options, as different support tiers offer varying response times and levels of assistance.

The marketplace agreement being accepted and then immediately terminated suggests an automated validation failure with the payment instrument. Working directly with AWS Support through your existing case is the best path to resolve this, as they can review your specific account configuration and payment setup.
