I've been making requests to the Product Catalog Products API using this URL:

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

Until recently, everything worked fine, but now the response only returns the name field. Here's an example of the response I'm getting:

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

The fields such as description, price, visibility, and others are missing. Has anyone encountered this issue, or are there changes to the API that I may have missed?

The operation failed with an error. Unsupported get request. Object with ID '6473825786074581' does not exist, cannot be loaded due to missing permissions, or does not support this operation.

We're using leadgen_id with URL https://graph.facebook.com/v20.0/{lead-id}/ and it's been working fine for our pages all along, but suddenly today we can't retrieve lead information even when we have access. This happens to all leads it seems. The last issue we had with FB leads are webhooks not being triggered. Now this seems to be a more serious one as we can't even use an alternative automation to get the lead info automatically as they're not being pulled from the API.
