Fixed taskId being null. For some reason, the task's execution is a child execution of the execution that set the variable. Therefore getVariableLocal() cannot find the value because it only looks for the value in the child execution's (local) variable store. GetVariable() on the other hand, does check parent executions for values so using the DSF API's variables, the child execution can find the value in the parent execution
