What leads to this error? Can you give some of the background of what you or your users do before getting the error above? What are the steps taken to reproduce?

Did this work before? What changed before it stopped working?

Are users adding things to their cart and then seeing this?

That error happens when a user attempts to check out and there are no items selected in the invoice/shopping cart:

if ( !\count( $invoice->items ) )
{
	\IPS\Output::i()->error( 'your_cart_empty', '2X214/2', 403, '' );
}
