My apologies. What you posted is very generic type of error. What I can tell only is that you had a NullPointerException in a workflow expression. What is more useful is which job failed in what workflow. You should be able to tell this by looking at the WTPropagationQueue and there should be a failed entry. It should lead you to the workflow and the step that failed. Then you need to look at the code expression in that step for what could have cause the error. This could be data related or some case that was not handled. Workflow code should be very robust and handle as many exception as possible gracefully so the workflow remains running.
