Describe the bug you're encountering

Hi, I generated the server code (nodejs-server) using the above yaml from Swagger Editor and was encountering CORS errors when I tried to call the api from an angular client.

I've installed cors package (https://www.npmjs.com/package/cors) and added the following in the index.js file and still encountering the same error.

I've also tried using other methods (as shown below) but still getting the same error: app.use(function (req, res, next) { res.setHeader('Access-Control-Allow-Origin', '*'); res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE'); res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type'); res.setHeader('Access-Control-Allow-Credentials', true); next(); });

Any idea on how to resolve this?
