'npm run build' gives me uncaught syntax error: Unexpected token '<' when I try to render the html file for my single page react app

Question

Here is what the package structure looks. Server folder contains the flask code, the src folder contains react code.

I have a Flask server with a react app. When I run the npm build script, it builds the 'build' folder. When flask attempts to render the html for my react app, I get the error for the Unexpected token '<' for 2.ed52de7f.chunk.js. It seems rather simple, but I have been stuck on this for a while and I desperately need help. The app renders fine when I open it using 'npm run start'.

I basically create-react-scripts and downloaded a a few other dependencies using npm install *package name*. — Andrew Desousa, Oct 18 '19 at 00:04

Unexpected token '<' for 2.ed52de7f.chunk.js

This means the request to get the static js file returns a HTML instead of javascript. You can do following things:

Check the url of chunk.js again, make sure it point to correct server
Trying to request that js with its url you will figure out the error

Hope this help
