Resource handler returned message: ECS Deployment Circuit Breaker was triggered. (HandlerErrorCode: GeneralServiceException)

Goal: I am attempting to run a simple NodeJS application with two routes: '/' which displays "Hello, World!" and '/health' which returns a status code of 200 along with a message.

Problem: I keep getting this error message: Resource handler returned message: "Error occurred during operation 'ECS Deployment Circuit Breaker was triggered'." (RequestToken: 9d7b28d1-2a1f-ed3f-3764-3da55e89b691, HandlerErrorCode: GeneralServiceException).

Tried: I attempted to resolve the issue by removing the existing cluster and service. I then proceeded to create a new cluster and service, starting from scratch, utilizing the provided task definition (shown below).

Certainly: Could someone please assist me in identifying the cause based on the clues I provided here? I need guidance on where to look and what to fix. Your assistance in troubleshooting is greatly appreciated. Thank you for taking the time to help with my issue.
