No 'Access-Control-Allow-Origin' header is present on the requested resource. NodejS Express

I am getting this error

(index):1 Access to XMLHttpRequest at 'https://example.com/crm/addlead' from origin 'https://abc.examplehosting.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

i have added this code as well in my app.js

app.use(function (req, res, next) {
    res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
    next();
   

});

Please suggest what could be the issue.

You need to install cors CORS.

const cors = require('cors')

var corsOptions = {
  origin: '*',
  optionsSuccessStatus: 200 // some legacy browsers like IE11
}
app.use(cors(corsOptions));

Try adding cors layer to your app,

npm install --save cors

// In your server file
var cors = require('cors');
...

app.use(cors());
