Is there a way to determine the root cause for 'Unsupported get request' when accessing a Facebook Page -

this stack overflow question illustrates various reasons why facebook graph api may limit access facebook page: graph api returns 'false' or 'unsupported request' accessing public facebook page

however, question ways figure out exact root restriction cause (graph api, facebook ui, etc.) when can access facebook page user access token , not app access token. i'm scraping info facebook pages , want able tell page owners specific restriction needs adjusted create page visible our app.

these restrictions mentioned in stack overflow thread:

age restriction country restriction alcohol unpublished - "is_published" field in page

are there others? how check first 3 if restrictions in effect?

fyi, current facebook page i'm trying figure out why user access token works , not app access token "forestsociety" facebook page.

thank in advance!

no, reason cannot access piece of content intentionally not revealed -

you should able access piece of content via id if received object id api phone call (e.g. if inquire user's feed , post id, post id should accessible directly), if seek access arbitrary id , don't have permission to, reason intentionally not revealed
