When synchronizing with the WordPress online store, prices and stock balances from 1C are not uploaded. What is the problem?

Question

Data synchronization

Installed the WooCommerce module and 1C:Enterprise/1C:Enterprise Data... configured the exchange node with the site. All products are uploaded to the site, except for availability and prices.
When I select "Agreement prices and stock balances" in the "Exchange node with the site" section, an error occurs during unloading:

Also, when I export all the data for the test to an XML file, there is such a field: International Abbreviation = "-"
Maybe this is the problem.
When exporting, even to an XML file, there is no unloading of prices and the balance in the warehouse, since synchronization is successful only without the checkbox "Prices according to agreements and the balance of goods in warehouses"
