Facebook Pixel Microdata Error: Missing "id"

I am working on a clients site trying to sync her Squarespace products with Facebook Catalogue.

I have followed all the steps as instructed but when I use the Microdata Debugging Tool it says the "id" is missing (see screenshot of error message).

I have checked all products in the store and they all have a product id (see screenshot of .csv product file). I tried reloading the Facebook Pixel to try refresh the information and that has not worked either.

Any insights where the "id" information is meant to come from and how I can enter this into the Squarespace store?

Thanks
