I am facing this error for testing the senario SN005 “Item 1: 0091 Extra tax provided where sale is of reduced rate goods. Please verify if provided sale type is for Goods at reduced rate.“. Below is my JSON response:

Even though the extraSale sent is empty string as per the documentation “0091: Extra tax must be empty.“
