I have a question about AWS Amplify when deploying. I’ve successfully deployed my application with a custom domain but there are couple things that I want to know. Here’s the procedure I did, and what’s happening here:

1. I have 2 separated repositories for the Frontend and the Backend.
2. I’ve also deployed 2 repositories in Amplify.
3. Frontend is successfully deployed but the Backend failed. Even though, my application is working. For example, the data from the Backend is displaying correctly.

Questions:

1. Why is it working?
2. How is it working when the repositories are deployed separately. I’ve never merged them together. I’ve did the domain settings in Frontend server.

I could provide more information if needed. Thanks!

Tools I used:
Frontend: React
Backend: Express
