Hi Aman,

Your encoded query appears to be partially escaped and is probably being ignored, though I'm not certain why the NullPointerException and not just a full incident query. You could replace those occurrences of %3D with =

Or alternatively unescape the encoded query string

   incquery.addEncodedQuery('active=true^state<6^NQactive=true');


or


   incquery.addEncodedQuery(unescape('active%3Dtrue^state<6^NQactive%3Dtrue'));
