Amazon Q Developer Pro subscription fails - "Failed to create Kiro subscription" with $4800 startup credits

Question

**Issue:** Amazon Q Developer Pro subscription creation consistently failing despite correct configuration and active startup program credits.

**Error Message:** 
"Failed to create Kiro subscription for X users. An error occurred while trying to create Kiro subscriptions."

**Account Configuration (All Verified ✅):**
- Account ID: 446503125838
- Region: us-east-1
- IAM Identity Center: Organization instance (ssoins-72235543b09370dd)
- Organization ID: o-skypl28ya0
- Instance Type: Organization instance (NOT Account instance)

**Startup Program Details:**
- Amazon Kiro startup program: $4,800 credits active
- Credit ID: 10063326300
- Valid until: June 30, 2027
- Status: Active and unused

**What I've Verified:**
✅ Organization instance of IAM Identity Center (not Account instance)
✅ AWS Organizations enabled with ALL features
✅ Users are ENABLED in IAM Identity Center  
✅ Correct region alignment (us-east-1)
✅ Administrative permissions
✅ No billing restrictions or overdue balances
✅ Service principals properly configured

**Error Pattern:**
- Occurs at final assignment step when adding subscribers
- Consistent failure across multiple user addition attempts
- Console URL: https://us-east-1.console.aws.amazon.com/amazonq/developer/home?region=us-east-1#/kiro/users

**Similar Cases Found:**
Based on other re:Post threads, this appears to be a backend provisioning issue where the `q:CreateAssignment` API fails silently, requiring manual intervention from AWS internal engineering team.

**Questions:**
1. Is this a known backend provisioning issue with Amazon Q Developer?
2. Does this require AWS Support escalation to Marketplace/IAM Identity Center team?
3. Are there any additional configuration steps needed for startup program credits?
4. Has anyone successfully resolved similar "Failed to create Kiro subscription" errors?

**Business Impact:**
Cannot utilize $4,800 in startup program credits until user subscription creation is resolved.

Any guidance or similar experiences would be greatly appreciated!

I understand you're experiencing a "Failed to create Kiro subscription" error when trying to set up Amazon Q Developer Pro subscriptions, despite having verified your configuration and having active startup program credits.

Based on the symptoms you're describing—particularly the failure occurring at the final assignment step when adding subscribers—this does appear to be a backend provisioning issue that requires AWS Support intervention. The error pattern you're seeing, where the subscription creation fails consistently despite correct configuration, typically indicates an issue that cannot be resolved through console actions alone.

For this type of issue, I recommend taking the following steps:

**Immediate Action:**
Contact AWS Support through the AWS Support Center (https://console.aws.amazon.com/support/) and create a new support case. When creating your case:
- Select "Account and billing support" as the case type
- Choose "Amazon Q" as the service
- Provide the technical details you've already gathered (though please avoid including your account ID or other sensitive information in any public correspondence)
- Request that the case be routed to the team that handles Amazon Q Developer provisioning issues

**What to Include in Your Support Case:**
- Description of the error message you're receiving
- Confirmation that you're using an Organization instance of IAM Identity Center
- Details about your startup program credits
- The specific step where the failure occurs (user assignment)
- Any error codes or additional details from browser developer tools if available

**Regarding Your Startup Credits:**
Your startup program credits should be applicable to Amazon Q Developer Pro subscriptions. However, the subscription creation failure needs to be resolved first before the credits can be utilized. The support team will be able to verify that your credits are properly configured and investigate any backend provisioning issues.

Since this appears to be a service-side issue rather than a configuration problem on your end, AWS Support will need to engage with the internal teams responsible for Amazon Q Developer provisioning to resolve this for you.
