Camunda Platform 8 Zeebe client process failing

HI ,

We are planning to migrate from camunda platform 7 to camunda platform 8.
so we started evaluating the changes and thus started with GitHub - camunda-community-hub/camunda-7-to-8-migration: A modeler plugin to convert BPMN files from Camunda Platform format to Camunda Cloud (Zeebe) format

1.I am just running “sample-process-solution-migrated” in my local while connecting to camunda zeebe engine created in camunda cloud cluster.
I have setup zeebe.client.cloud.clusterId clientId, clientSecret, region.
While startup its failing with
rg.springframework.context.ApplicationContextException: Failed to start bean ‘zeebeClientLifecycle’; nested exception is java.lang.NullPointerException: target
