Afandee Facebook pixel & Ads

Hello,

we are getting these errors:
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.
-A required field is missing: price
Products need to have prices to run in ads. Include a price for each product in your data feed file and upload it again. Prices must include cost and an ISO currency code (for example: 10 USD instead of $10 for American dollars).
-A required field is missing: availability
Products need to have availability listed to run in ads. Include the current availability for each product in your data feed file and upload it again. You can only add the supported values "in stock", "out of stock", "preorder", "available for order", "discontinued", "pending" in US English under the "availability" column.

Warnings
A product is missing a field: google_product_category
Without google_product_category information, your products may not appear the way you want them to.
