Hi JHF,

Thank you for replying. The WebSocket connection is getting established, and I am getting the connection ID. OnMessageCB is working. Expectation is --

1.User clicks on the search link.

2.The search api is invoked and receives 504 Gateway Timeout error. As the data which needs to be fetched is large.

3.WebSocket will send a message containing AWS S3 url which will be invoked by the browser and the searched data will be received.

This another message I am not receiving, actually OnMssageCB is not getting called. If something is needed to be done in the script?
