Error : While posting review on Facebook page

I'm getting an error while posting a review on Facebook page using a "POST" method.

{ "error": { "message": "Unsupported post request. Object with ID '311823882006106' does not exist, cannot be loaded due to missing permissions, or does not support this operation. Please read the Graph API documentation at https://developers.facebook.com/docs/graph-api", "type": "GraphMethodException", "code": 100, "error_subcode": 33, "fbtrace_id": "Ar6_ieLkr0wegRXZ4uQtkoG" } }

But it was working good when I'm getting a review from Facebook page by using "GET" method
