Hi @countnazgul,

Thank you for your help. I got the csrf token and was able to connect to the engine.

The example, you are following, is for Node.js.
In browser environment you cant set the web socket headers. The browser will send the relevant headers with your request. If the relevant headers/url parammes are not passed then the connection will fail.

If your case you should authenticate first, get yourself csrf token and then open enigma connection (passing the web intergration id and the csrf token in the web socket url)

Have a look at this tutorial https://qlik.dev/tutorials/build-a-simple-web-app
