Why is my deployed app not found on AWS for Shopify?

[resolucionenlin]

Hello community,

I'm reaching out for assistance with an issue I'm facing with my Shopify app deployment. We've developed a Shopify app that functions as an iframe displaying our Angular front end. Locally, everything works seamlessly when tested with `npm run dev`.

Here's the setup:
- We deployed the app on AWS ECS, running the Docker image.
- We use Route 53 to map a URL to an API Gateway to access the service.

However, when attempting to install the app on my development store, I receive a JSON message saying: `{"message":"Not Found"}`. The request log shows:

```

Any insights or guidance on resolving this issue would be greatly appreciated.

Thank you!
