## Expected Behavior I'm using temporal-testing and when I query running workflows: ```java List executions = client.getWorkflowServiceStubs() .blockingStub() .listOpenWorkflowExecutions( ListOpenWorkflowExecutionsRequest.newBuilder() .setNamespace("default") .build() ) .getExecutionsList(); executions.forEach(execution -> { System.err.println(execution.getExecution().getWorkflowId()); System.err.println(execution.getMemo()); });...
