Trouble with "Deploy a Web Application on Amazon EC2" training module

Hello! I assume your question is in reference with the training module here. I see that the module does mention Go to the file /lib/cdk-ecs-infra-stack.ts. Instead could you go to the file at ./lib/ec2-cdk-stack.ts and continue with the steps outlined in the module. Please give this a try and let us know if you are running into any issues. That being said, I apologize for the inconvenience and have provided feedback to documentation team to have this corrected.
