[Dynamics 365 Online] Tracing Service and Workflow Context Null on Workflow Activity

Hi,

Currently I need help for Workflow Activity. Please take a look at code below:

protected override void Execute(CodeActivityContext executionContext)
{
	// Create the tracing service
	ITracingService tracingService = executionContext.GetExtension<ITracingService>();

	if (tracingService == null)
	{
		throw new NullReferenceException("Failed to retrieve tracing service.");
	}

	tracingService.Trace("Entered ProposeCaseActivity.Execute(), Activity Instance Id: {0}, Workflow Instance Id: {1}",
		executionContext.ActivityInstanceId,
		executionContext.WorkflowInstanceId);

	// Create the context
	IWorkflowContext context = executionContext.GetExtension<IWorkflowContext>();

	if (context == null)
	{
		throw new NullReferenceException("Failed to retrieve workflow context.");
	}

	tracingService.Trace("ProposeCaseActivity.Execute(), Correlation Id: {0}, Initiating User: {1}",
		context.CorrelationId,
		context.InitiatingUserId);

	IOrganizationServiceFactory serviceFactory = executionContext.GetExtension<IOrganizationServiceFactory>();
	IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);
	CrmServiceContext serviceContext = new CrmServiceContext(service);
}

Why do the tracing service and also the workflow context are null? What is happening? Doesn't it the default code for a Dynamics Workflow Activity?

Thanks in advance.
