this is the code there in the filter node input

From the error it looks like one of the filters is null. Also I dont see any filter relating to ihubid >  configured in the above. So start checking filter blocks to find which one is causing issue. 

Also did you check the tomcat stdout log file to see if more details were there in log about the error?
