Why does it give an error "Argument 'deliveryId' is null or empty" when trying to calculate an order?

Question

Hello.

Problem with the sale.order.ajax component (we use the old version) When trying to calculate the cost by the delivery service, the Russian Post gives an error "Argument 'deliveryId' is null or empty"


I found where the deliveryId is set, set it to check the delivery id, but it did not help .

There are no php errors, I can not figure out how to find the roots of this error.
Help me to understand.

why is it customizable if you need an "automated delivery service" with a mail handler for mail
