API Connector sending null for all values

So I thought I had solved this problem in my previous post by changing the body type from JSON ot form-data, but the problem continues. Same API, different call. My other calls work perfectly fine and my settings are matched everywhere except what needs to be different. I’m tearing my hair out over this!

Working call:

Not working call:


For what it’s worth, the call in question is working perfectly fine in Postman as well.
