When trying to import a csv of updated product quantities and cost, Odoo process for about 30 seconds, then just says, "Odoo Server Error." 

This is what I'm trying to import (I'm ignoring all columns except "ID", "supplier_integration_ids/available_quantity", and "supplier_integration_ids/cost_value"):

id,supplier_integration_ids/id,supplier_integration_ids/product,supplier_integration_ids/nts_supplier_id,supplier_integration_ids/available_quantity,supplier_integration_ids/cost_value,default_c
