Generate steps for WebSocket traffic

Hi,

We tried to record the aapplication developed in Angular js, Node JS,Canvas, Qlik sense Technology for the web + web socket communication in web protocol. It seems the web socket communication are not captured with web protocol in LoadRunner even after checking Generate steps for WebSocket traffic option in Recording Option,

The socket communcation are getting captured in neoload(But still some issues available). We need to confirm whether there is any option to record the web+web socket communication in loadrunner.

Also any code client side code avaiable for generating web_socket_key authentication which really helps.

Regards,

Raghul M
