Description: |
  AWS CloudFormation template for Mock WebSocket API Gateway. When deploying this stack please remember to check the option:
   - I acknowledge that AWS CloudFormation might create IAM resources.
  This template can help you to solve issues like:
  - CloudWatch Logs role ARN must be set in account settings to enable logging
  - Execution failed due to configuration error: statusCode should be an integer which defined in request template
  - This custom domain name cannot map to WEBSOCKET protocol APIs
  - Error during WebSocket handshake: Unexpected response code: 500
