422 error when creating server

[ZikaCodez]

I tried using this JSON object to create a server, however, I get a 422 error in return. I checked my API token and it's correct and has all permissions enabled, as well as other operations work without any issues.

Retrieve the body response of the error and it would tell you what you're missing. There's a required variable that's not passed.
