If you encounter an error (An Error Occurred when attempting to: When Creating HypaShip Shipment! Error: Object reference not set to an instance of an object.) while shipping with APC (HypaShip), check that the order details, including Address Details, Packing Notes, and Delivery Notes, do not exceed 35 characters. Also ensure no special characters (&, £, ?, !, etc.) are used in the address details.
