Catalyst ZCQL query not working in Node function

I am trying to get the average of a column from Datastore table using ZCQL query. The column is of Boolean Datatype. When I tried executing the ZCQL query from Query Console, I am the getting the proper response. Refer Screenshot belowZCQL

But when I try the same query from the Node function I am getting the following error:Function

I double checked the query but I am still getting the same error. Can someone help me resolve this?
