Here is a workaround. Delete “proxy”: “http://localhost:6000”. Install package http-proxy-middleware with command npm install http-proxy-middleware –save. Create a file setupProxy.js inside your src folder or the root of your folder. Add these lines inside:
const { createProxyMiddleware } = require('http-proxy-middleware');
module.exports = function(app) {
app.use(
'/api',
createProxyMiddleware({
target: 'http://localhost:6000',
changeOrigin: true,
})
);
};
Now, run your app. It should work.
