I purchased this Braintree Payment Acquirer App from Webkul: https://www.odoo.com/apps/modules/9.0/payment_braintree/

To me it looks like there's no sales order created. I didn't do anything but put in my API keys to connect to my Sandbox account. Since I purchased this module more than 3 months ago, Webkul refuses to help me unless I pay for their extended support. Any ideas?

Straight out of the box I get this traceback error after inputting test credit card details:
