The error means that there was no shipping rate table found on your eBay account but the shipping rate table is currently enabled on this configurator for Domestic and/or International Shipments. If there are no shipping rate tables created on your eBay back-end then both these options should be disabled in the configurator:
Settings > eBay Configurators > Shipping
Otherwise, you need to login into your eBay account and create a shipping rate table(s) there. Note that for International Shipping Services locations must be specified in the configurator. You can use the domestic shipping rate table to set the amount you charge for shipping by shipping method and destination. Shipping rate table must be configured on eBay.
