All of our tickets come in from a service account email. What I would like to do is have the automation scan the description for a user email address, and then replace the reporter with the display name of that email address. I am able to get the API call for displaying user info to work in Postman, but I'm not able to see what's going wrong in the scripting for the Automation. Attached is a screenshot of the json I have cobbled together to attempt this. The testing always results in "Anonymous User" which is telling me either it's not finding the email address or the accounts associated. Please let me know any suggestions.
