@Venkatesh GUDEENTI have you considered transforming the value back on the client? The reason that the transformation is in place is to make sure the content does not invalidate the response by adding special characters.
The problem we have here is with custom DX API attributes. As Pega DX is not supporting to return the when condition logic, we are using DX attributes to send the Boolean expression to client side in JSON.
For example – FieldID1 == “yes” && FieldID2 == “no”
Pega is converting the above Boolean expression to - FieldID1 == "yes" && FieldID2 == "no"
It’s difficult for front end developers to parse this and apply logic.
