Bedrock Model Subscription Loops and INVALID_PAYMENT_INSTRUMENT Error

Question

Hello,

I need assistance regarding the new model subscription process in Amazon Bedrock.

Previously, I was using the Sonnet 3.7 model, but it became non-functional overnight. I attempted to switch to Sonnet 4.6, following the new automatic subscription method. Despite having an AdministratorAccess account, I spent several days receiving marketplace subscription authorization errors when trying to use the Playground.

The situation has now evolved into an INVALID_PAYMENT_INSTRUMENT error. Interestingly, I can use a model once in the Playground, but as soon as I reopen it, the error reappears (this happens once per model).

My payment profiles for Marketplace (both Inc. and EMEA) are valid. Each time I attempt a subscription, I receive a confirmation email stating that I have accepted a Marketplace offer, followed a few minutes later by another email stating that the offer has expired.

This is currently blocking our production environment. I have opened two support tickets (Case IDs: 177513171600519 and 177540438500931) but have received no response. My Account Manager has also been unresponsive.

Have you encountered this issue before? Do you have any insights on how to resolve this subscription loop?

Hi, this is a known issue with the new Bedrock Marketplace subscription process, especially when switching between Claude models.
Your payment profiles are valid, but the subscription gets stuck in a loop with INVALID_PAYMENT_INSTRUMENT loop. Since you've already opened two cases, reply on both and ask for escalation to the Bedrock Marketplace team. This usually gets fixed only after escalation.

I understand you're experiencing a frustrating issue with model subscriptions in Amazon Bedrock. While I don't have specific information about the INVALID_PAYMENT_INSTRUMENT error or subscription loops you're describing, I can suggest some troubleshooting steps based on general Bedrock managed entitlements issues.

For billing-related problems that prevent model usage, you should verify that your management account has a valid payment method configured. Even if your Marketplace payment profiles appear valid, there may be an underlying issue with how the payment instrument is being processed for Bedrock subscriptions specifically.

Since you've already opened support cases, I recommend escalating through the following channels:

1. **Check the AWS Service Health Dashboard** to see if there are any ongoing issues with Marketplace or Bedrock services that might be affecting subscriptions

2. **Review your AWS CloudTrail logs** - Search for events related to Marketplace and Bedrock, looking specifically for error messages or failed API calls that might provide more detail about the INVALID_PAYMENT_INSTRUMENT error

3. **Continue following up with AWS Support** on your existing cases, emphasizing that this is blocking your production environment. Request escalation if you haven't received timely responses

The pattern you're describing - where subscriptions appear to succeed initially but then expire shortly after - suggests there may be an issue with the payment validation process rather than your actual payment methods. This would require AWS Support to investigate the backend subscription and billing processes for your specific account.

Given that this is production-impacting, continue to emphasize the urgency with your support cases and Account Manager.
