Hi koushik, sorry for late reply.
Your Nebula kernel version seems to be incorrect. The latest release is 3.6.0. Additionally, this error message typically occurs when the service configuration is incorrect. If you are deploying NebulaGraph service using Docker, do ensure that Spark is also in the same container network to avoid communication issues that may lead to errors.
