An error occurred (InsufficientInstanceCapacity) when calling the RunInstances operation (reached max retries: 2): We currently do not have sufficient m6id.xlarge capacity in the Availability Zone you requested (us-east-2c). Our system will be working on provisioning additional capacity. You can currently get m6id.xlarge capacity by not specifying an Availability Zone in your request or choosing us-east-2a, us-east-2b.: exit status 254 [owner=test-eng]
