AppRunner Deployment Configuration Fix

I've developed and deployed a Docker image to ECR and AppRunner, but I'm facing deployment issues in AppRunner service. The error is a configuration error, specifically an incorrect port configuration. Despite specifying the port configuration in the AppRunner settings, the deployment is still failing.

Ideal skills for this project include:
- Docker
- AWS AppRunner
- Troubleshooting configuration errors
- Networking knowledge related to port configuration

I need an experienced professional who can swiftly diagnose and fix this issue, allowing my Docker image to successfully deploy in AppRunner.
