Facebook graph api Query Unsupported get request code 100

Question

Can someone help me with an answer? Why do some pages on Facebook Graph return

{ "error": { "message": "Unsupported get request.", "type": "GraphMethodException", "code": 100 } } 

the page exists: https://www.facebook.com/RoyalCaninRomania and the return of the facebook graph: http://graph.facebook.com/RoyalCaninRomania or graph.facebook.com/669235549759213

but the developer is fine: developers.facebook.com/tools/explorer/?method=GET&path=669235549759213 it generates a url graph.facebook.com/669235549759213, but this url generates an error message in the browser
