Error occurred while trying to proxy: localhost:3000/

Error occurred while trying to proxy: localhost:3000/ on http://localhost:3000/auth/login/. The error most likely came from setupProxy.js

const { createProxyMiddleware } = require('http-proxy-middleware');

module.exports = function (app) {
    app.use('/auth/**',
        createProxyMiddleware({
            target: 'http://localhost:5000'
        })
    );
};

or package.json
