API giving error when adding discount code

[aaron3232]

We use a platform called Event Espresso and have been running event registration with Square as our payment gateway. All was working well but we tried adding a discount code and now anytime any discount code is applied you get an error that says "Configuration not setup correctly. Money must be a non-negative" But clearly the discount isn't greater than the ticket price. 

Also, if we enable Paypal as the payment gateway it has no problems processing the discounted ticket. It only happens with square as the payment gateway and only when a discount is applied. Below is the API log report for reference.

Does the discount that you are trying to add to the order for the Checkout API have a " - "?
We do not allow for negative numbers when creating an order.

I hope this helps, @aaron3232!
