How to deploy docker-compose flask project to AWS ECS in gitlab CI

Question

My project is a flask project using docker-compose. And source code is in GitLab. I wanna auto-deploy to ECS with GitLab CI. Also, docker images are in ECR. But I faced following error.

Cluster creation succeeded.

I've attached configuration files. I think, I missed some AWS configurations, but I can't find mistakes. How can I fix it?
