TypeError: Cannot read property 'controls' of undefined

Hello everyone,

I'm getting the following error in the Quote Line Detail form while trying to change the values of Quantity and Unit Price field. The form was perfectly working before our system shifted to Unified Interface recently.

I found that the following onChange function in the QuoteLineDetailInitialization.js is being called on change of Quantity and Unit Price field values.

The above lines of code then call the following functions in UIUtils.js

The formFieldHasValue function gets field name in the formContext parameter instead of formContext object and 0(null) in the field parameter, that's why in the next line it can't retrieve data and gives the error. The same thing happens in disableAttribute function as it doesn't get formContext object in the first parameter. Both the files are system defined scripts so we are unable to make any changes there. I checked execution context as first parameter option from every function call in the form properties but the error persists. Can anybody help me with this ?

Thanks in advance.
