Hi All ,

Last week I had written a client script with script include to fetch the assignment group based on the fields "Business Application" and "Business Process" in the incident form. It was working fine .

But suddenly from today morning getting the below error when i modify the  fields "Business Application" and "Business Process" : 

class com.glideapp.questionset.SelectQuestion cannot be cast to class com.glideapp.questionset.LookupSelectQuestion (com.glideapp.questionset.SelectQuestion and com.glideapp.questionset.LookupSelectQuestion are in unnamed module of loader com.snc.orbit.container.tomcat8.Tomcat8$OrbitTomcat8ClassLoader @1282017): java.lang.ClassCastException: class com.glideapp.questionset.SelectQuestion cannot be cast to class com.glideapp.questionset.LookupSelectQuestion (com.glideapp.questionset.SelectQuestion and com.glideapp.questionset.LookupSelectQuestion are in unnamed module of loader com.snc.orbit.container.tomcat8.Tomcat8$OrbitTomcat8ClassLoader @1282017): com.glideapp.servicecatalog.LookupSelectProcessor.initVariable(LookupSelectProcessor.java:99)
