The «%cart_id%» value of a «route/data/parameter» branch of an webapi.xml works only for registered customers, not for guests

Context: How is a «route/data/parameter» branch of a webapi.xml interpreted?

mage2pro/core/blob/2.4.27/Payment/etc/webapi.xml#L10-L14


	<route url='/V1/df-payment/mine/place-order' method='POST'>
		<service class='Df\Payment\PlaceOrder' method='registered'/>
		<resources><resource ref='self'/></resources>
		<data><parameter name='cartId' force='true'>%cart_id%</parameter></data>
	</route>

It is impossible to use the following line for the guest customers:
