react-dashboard | isomorphic admin dashboard template | Frontend Framework library

I'm having some trouble connecting to the cube.js backend on AWS serverless and executing the /cubejs-api/v1/load request in the frontend dashboard. I keep getting {"error":"Continue wait"} instead of a result returned. I am following the react-dashboard guide for authentication but deployed using the backend cube.js serverless AWS template. This is what my main cube.js file looks like.:

My project includes cube.js backend and react frontend. I was able to set up CICD using aws amplify for the front end but I am unsure if I can deploy cube.js on aws amplify.

In the local environment I first run 'npm run dev' to run the backend which starts the service on localhost:4000 and I start the react project with 'npm start' and it runs on localhost:3000. I would like to build and deploy both backend and frontend using aws amplify

My project is set up similar to this example https://github.com/cube-js/cube.js/tree/master/examples/react-dashboard

In aws amplify, I have the build settings for my frontend as below

I have a site developed entirely using flask. It uses a Blueprint called dashboards, which hosts some views to access different visualizations, i.e dashboards/

I store my dashboards with an id, a name and the group it belongs to, so users can only access the visualizations from the group they also belong to.

(This is my unexperienced approach to solve this problem, so I'm also open to suggestions of a better design pattern to achieve this.)

My project kinda looks like this
