sqs_objects is not defined

In detail view of AOS_Quotes module, i am trying to add a service/product line item in a quote but I get an error on the console saying sqs_objects is not defined and the fields to be added dont show

I am using Version 7.6.3
Sugar Version 6.5.23 (Build 1061)

Line 94 of line_items.js

When you figure this out please let me know.
