> A valid StartToClose or ScheduleToCloseTimeout is not set on workflow task. It means that one of the activities doesn’t specify one of the required timeouts. ---

``` @RegisterExtension public static final TestWorkflowExtension testWorkflowExtension = TestWorkflowExtension.newBuilder() .setWorkflowTypes(ReplaceArtefactWorkFlowImpl.class) .setDoNotStart(true) .build(); ArtefactGatewayActivity artefactGatewayActivity = Mockito.mock(ArtefactGatewayActivity.class); BundleHubActivity bundleHubActivity = Mockito.mock(BundleHubActivity.class); ``` I’m using like above to mock my activites. I’m now specifiying the StartToClose or ScheduleToCloseTimeout by mocking the workflow config class.FYI i have workflow config file in which i specify above properties WorkflowConfig workflowConfig = Mockito.mock(WorkflowConfig.class); Mockito.when(workflowConfig.getActivityStartToCloseTimeoutMinutes()).thenReturn(20L); Mockito.when(workflowConfig.getActivityScheduleToCloseTimeoutMinutes()).thenReturn(20L); Mockito.when(workflowConfig.getWorkFlowExecutionTimeoutMinutes()).thenReturn(60L); After doing the above things I’m receiving the following error when i’m mocking one of my activities call. Method threw ‘io.temporal.internal.sync.DestroyWorkflowThreadError’ exception. Also the acitivity is showing Method threw ‘java.lang.IllegalArgumentException’ exception. Cannot evaluate jdk.proxy2.$Proxy90.toString(). This is i’m receiving on debugger mode. Please help here. Also my activity calls are in different class than the workflow one. For example if there are two classes A and B then class A is my WorkflowImpl class and in class B I have a method in which my activity calls are present. So i’m calling that method of class B in class A. Can this be a cause of problem ? ---

Got this solved. I was missing the one mock.
