@im-siva are you running backend of this project?

By default when you try to run this project you need to run client in a separate window and then run backend with F5 command either in VS code or IDE. What you described sounds like backend isn't available.

closing for now. Awaiting confirmation.

Hi, I'm getting this same error and I'm not sure how to rectify it. Any help would be appreciated.
