Hi-
I'm trying to add a PUT request to my payment screen (AR302000). However, when I test it using Postman, I encounter the following error, and I'm a bit stuck on where to find the issue and fix it. Here's the error message and the JSON data. If anyone could assist me in identifying what's wrong, I'd greatly appreciate it.
Thanks a bunch!
