AWS CDK Deployment Fails: Aurora PostgreSQL 13.7 Not Found (Service: RDS, Status Code: 400)

[rayl15]

Description

I encountered an issue while deploying the opa-platform stack using AWS CDK. The deployment fails with the following error:

❌ opa-platform failed: _ToolkitError: The stack named opa-platform failed creation, it may need to be manually deleted from the AWS console: ROLLBACK_COMPLETE: Resource handler returned message: "Cannot find version 13.7 for aurora-postgresql (Service: Rds, Status Code: 400, Request ID: bbcaba24-4d94-44d4-a67d-7f88c6f340b1)" (RequestToken: c24ca99a-b600-5dbf-65b5-7987be31de0a, HandlerErrorCode: InvalidRequest)

It appears that Aurora PostgreSQL version 13.7 is no longer available, causing the stack creation to fail.

Versions

• OPA plugin versions:

Reproduction Code

Steps to reproduce the behavior:

1. Run cdk deploy for the opa-platform stack.
2. The deployment fails with "Cannot find version 13.7 for aurora-postgresql" error.
3. The stack rolls back, causing the deployment to fail.

Expected behavior

The opa-platform stack should deploy successfully, using an available Aurora PostgreSQL version.

Actual behavior

1. The stack fails with Cannot find version 13.7 for aurora-postgresql.
2. It appears that Aurora PostgreSQL version 13.7 is no longer supported in the selected AWS region.
