I have installed fresh magento 2.3.1 and tried to import stock, but every time I got error "Cannot get autoincrement value". The product is added to store, but Quantity is empty, and Salable Quantity is No Manage Stock. In inventory settings, I have set Manage Stock to Yes. Where is the problem with import, I have notice that for columns:
qty out_of_stock_qty use_config_min_qty is_qty_decimal allow_backorders use_config_backorders min_cart_qty use_config_min_sale_qty max_cart_qty use_config_max_sale_qty is_in_stock notify_on_stock_below use_config_notify_stock_qty manage_stock use_config_manage_stock use_config_qty_increments qty_increments use_config_enable_qty_inc enable_qty_increments is_decimal_divided website_id
All is empty. Anyone has faced same issue?
