When I list an item on eBay I get the error: Input data for tag <Item.ShippingDetails.ShippingServiceOptions.ShippingServiceCost> is invalid or missing. Please check API documentation

Most probably, you use a Custom Attribute to specify a Shipping Service Cost in your Shipping Policy tab and this Attribute is empty or has an invalid value in your product.

Please, check if the attribute you use in a Shipping Service Cost has a valid value.
