I have a Netlify project running which contains two git submodules. Module 1 is a frontend server running on React. Module 2 is an Express server that retrieves data and returns it. I am now trying to fetch a URL in order to retrieve the correct data from the backend server. But unfortunately I am getting this error: 'Unexpected token < in JSON at position 0'.
The only line in my _redirects file (located in public folder of frontend server) is now: /* /index.html 200
I have a proxy set to http://localhost:4000 (backend server) in the package.json of the frontend server.
Can someone tell me where the problem lays?
Backend Server
Router in the backend server
Trying to fetch data like this
This happens on the frontend server running on port 3000.
