Answer 1

i cleared it by including the following steps in my node.js

 app.use(function (req, res, next) {
        // Website you wish to allow to connect
        res.header('Access-Control-Allow-Origin', '*');
        // Request methods you wish to allow
        res.header('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
        // Request headers you wish to allow
        res.header('Access-Control-Allow-Headers', 'X-Requested-With,content-type');
        // Set to true if you need the website to include cookies in the requests sent
        // to the API (e.g. in case you use sessions)
        res.header('Access-Control-Allow-Credentials', true);
        // Pass to next layer of middleware
        res.header('Access-Control-Allow-Headers', 'Content-Type, application/json');
        next();
    });
