Currently I am doing a small POC using spring boot and getting the following error from Spring Zeebe Java Client, when trying to establish with zeebe cluster created using Camunda Trial account.
Following is the error.

What is the cause of this error, is due to incompatible zeebe cluster version and zeebe client?
For zeebe client I am using spring zeebe starter: io.camunda.spring:spring-boot-starter-camunda:8.3.1
Cluster Generation version: Camunda 8.3.3
