Error message Products without "id" information can't be uploaded.

I cant seem to get Facebook Micro data to accept that I have a unique SKU or id. Running it through Schema.org shows no errors.

Any help would be appreciated. I've cleared cache and tried using a code block but still no joy.

This is the error:

 

Errors

A required field is missing: id

Products without "id" information can't be uploaded. Please check that this field is included for each product in a separate, labeled column.

Same issue here. Anyone figure it out? @Kilbert @MBSQUARESPACE @jamesmurch 

Are you doing the import of products to Facebook catalog using the feed URL, not the website URL?
