Hey @Sravani! If you set up the Java SDK Quickstart, are you still running into this error there?

No, When I set up Java SDK Quickstart , I am not getting this error.

Got it, thanks for checking! In that case, it seems likely that there is an issue with your either your environment or your dependencies that’s resulting in this error. It’s hard for me to say exactly what it might be with the information provided, but I would recommend comparing the quickstart to your own project and trying to identify where that difference may be.
