Why task is getting created with null status

Hi,

After initiating process, task is getting created with null status, because of while doing any operation or fetching task list getting below error?

I am using .NET Zeebe client for creating starting the process. Also process instance is running successfully.
client
.NewCreateProcessInstanceCommand()
.BpmnProcessId(bpmProcessId)
.LatestVersion()
.Send();

Could you please help me the Task status, that why it is null?

I am using cluster configuration Zeebe 8.2.0-alpha2
