My POST Call Stopped Working

I’m getting the following error when initializing my API call:

This call worked in the past, but now I keep getting this error.
Here’s the call:

The call works in Postman.

Do you have a value for all the form fields?

I have at least one form field that I left blank and I have fields that aren’t on there. I can test to see if that’s the issue, but in Postman I didn’t have all the fields in and it still worked, and when it was working previously I didn’t have all the fields in.

Try making it optional and re-initialize.
