axios autohorization headers / CORS error - node.js

Question

I'm using react with axios to fetch some information. I'm sending JWT token to auth user and im geting response in console browser
"Access to XMLHttpRequest at 'https://beer-tonight.herokuapp.com/beer/getBeerStatus' from origin 'http://localhost:3000' has been blocked by CORS policy: Request header field authorization is not allowed by Access-Control-Allow-Headers in preflight response."
This is my code:
componentWillMount(){
let token = localStorage.getItem('token');
axios.get('https://beer-tonight.herokuapp.com/beer/getBeerStatus', {headers: {Authorization : 'Bearer ' + token}}).then(
result => {
console.log('yey');
});
}
Error:
When I am using POSTMAN I am getting proper answer.
Postman input:
p.s. i already added :
app.use((req, res,next)=>{
res.setHeader('Access-Control-Allow-Origin', '*');
res.setHeader('Access-Control-Allow-Methods', 'GET, POST, PATCH, DELETE');
res.setHeader('Access-Control-Allow-Headers', 'Content-Type, Authorisation');
next();

Answer 1

You've written Authorisation:
res.setHeader('Access-Control-Allow-Headers', 'Content-Type, Authorisation');
But the header is Authorization as you have used with axios, try changing that and seeing if it works then,

Answer 2

I believe the cors error that you are receiving is from your node.js api. (https://beer-tonight.herokuapp.com/beer/getBeerStatus)
Since the host do are not the same origin (beer-tonight.herokuapp.com does not match with localhost), you need to enable cors for your node.js server.
If you are using express:
const express = require('express');
const cors = require('cors');
const app = express();
app.use(cors());

Hapi.js:
server.connection({ routes: { cors: true } })

Once you have CORS enabled, everything should work smoothly. More on CORS
