problem transmitting erp bling inventory to prestashop - Error Services failed and returned an HTTP status of 500

[ingrid lodi]

Hello,
I made the integration of the prestashop store with the ERP bling up so everything is fine, but at the moment I'm going to pass the inventory to the prestashop store it returns the following error message -
There was an error while exporting products. Failed to export products. This call to PrestaShop Web Services failed and returned an HTTP status of 500. That means: Internal Server Error. -

 Unknown column id_country in field list. From Ps_Facetedsearch-> indexProductPrices () Query was: INSERT INTO `ps_layered_price_index` (id_product, id_currency, id_shop, price_min, price_max, id_country) VALUES (64, 3, 1, 30, 30, 21) ON DUPLICATE KEY UPDATE id_product = id_product

	help me please.
