Issues with Open Cloud ban API

I’m trying to ban users from my game using the new ban API with an external source, but the API responds with an error I do not understand. Does the ban API even support creating user bans?

{
	"code": "INVALID_ARGUMENT",
	"message": "Unable to read the request as JSON because the request content type '' is not a known JSON content type."
}

Please provide the script as this could be a scripting error. Also make sure studio is up to date.

This is not a roblox studio script, but it is an issue with the Roblox platform. I wasn’t sure where to put this.
