I started NiFi and then quickly went to the UI and right-clicked on a processor and tried to view Status History. I got back an error. The user-logs show the following (partial) stack trace: {code:java} 2018-09-19 13:20:19,928 ERROR [NiFi Web Server-24] o.a.nifi.web.api.config.ThrowableMapper An unexpected error has occurred: java.lang.NullPointerException.
