I'm doing a request to the Product Catalog Products API with this URL:

https://graph.facebook.com/v20.0/[PRODUCT_CATALOG_ID]/products?access_token=[ACCESS_TOKEN]&filter={"name":{"i_contains":"Agua"}}&fields=["retailer_id","name","description","price","visibility","inventory","url","image_url"]

Some days ago it stopped working, in the response i'm only reeiving the info of the name like this:

{ "data": [ { "name": "Agua" } ], "paging": { "cursors": { "before": [BEFORE_CURSOR], "after": [AFTER_CURSOR] }, "next": [NEXT_URL], "previous": [PREVIOUS_URL] } }
