Hi this happens when the front end and backend is running on different ports. The browser blocks the responses from the backend due to the absence on CORS headers. The solution is to make add the CORS headers in the backend request. The easiest way is to use cors npm package.

var express = require('express')
var cors = require('cors')
var app = express()
app.use(cors())

This will enable CORS headers in all your request. For more information you can refer to cors documentation
