Hi Yash I am not sure whether you have subscribed this mail list, hope you are(so add your personal mail box on cc list)
About this error, it seems you don't have an OAP server running at 127.0.0.1:11800. For the new users, I encourage you to use the quick start showcase, https://skywalking.apache.org/docs/skywalking-showcase/latest/readme/ Once you have a KinD/Minikube/k8s you could use one command to deploy all things out of box, and this demo app includes Spring-based Java service.
