Anna Manukyan reopened ISPN-6406:
---------------------------------


The issue still appears in case when the script is executed with mode=distributed.

There is no exception on server side, but on client side I am getting: 

   Message:
     java.util.concurrent.ExecutionException: java.lang.NullPointerException
java.lang.NullPointerException
   Stacktrace:
     undefined
