I am using IFS FSM to send an outbound message from our system to a customer’s ticketing system. I am trying to use value conversions to translate our request_unit.model_id to the customer’s system subcategory field. The lines have been set up, with some of the values below, however, when triggering this integration, the values provided are not being converted. 
 

This is the output provided by my tests below- you can see that the input is still the “value from” rather than the expected “value to”

  "request": {    "location": "0901",    "channel": "virtual_agent",    "category": "LAPTOP-GS",    "subcategory": "LAPTOP-GS",    "priority": "3"  }

How would I go about troubleshooting this to determine why it has not converted?
