Since today the following request

curl 'https://graph.facebook.com/v17.0/1799561253793262/products?access_token=$ACCESS_TOKEN&summary=&fields=id%2Cname%2Cprice%2Cretailer_id&filter=%7B%22retailer_id%22%3A%20%7B%22contains%22%3A%20%2243214b42-30fe-4306-bf44-10a46e68f105%22%7D%7D&limit=100' | jq '.data[]'

with same url decoded, for your reference and readability:

https://graph.facebook.com/v17.0/1799561253793262/products?access_token=$ACCESS_TOKEN&summary=&fields=id,name,price,retailer_id&filter={"retailer_id": {"contains": "43214b42-30fe-4306-bf44-10a46e68f105"}}&limit=100

does not return all requested product fields as per the request query parameters:

&fields=id,name,price,retailer_id

Instead the request only returns products with the field name:

{"data": [{"name": "Museau 400 g"}], ...}

Expected:

{"data": [{"id": "..........", "name": "Museau 400 g", "price": ....., "retailer_id": .......}], ...}

All graphi api versions are affected.

I kindly ask for your support.
