ePost Global Error at Booking: We expected status code 2XX but instead received status code 500
When trying to book an ePost Global shipment, it is most likely due to the Phone Number field for the receiver being blank.
Since ePost Global shipments require a recipient phone number, add it in the field and try booking the shipment again.
