Facebook Page Image returning null in FBSDKGraphRequest

Question

I am attempting to retrieve the image from a facebook page. I have retrieved the page ID, and now I need to use this ID to get the image from the page. I am using the following code:

let pictureRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: picPath, parameters: ["fields" : "data"], HTTPMethod: "GET")
                            pictureRequest.startWithCompletionHandler({ (connection: FBSDKGraphRequestConnection!, result, error) -> Void in
                                if (error != nil) {
                                    print("picResult: \(result)")
                                } else {
                                    print(error!)
                                }
                            })

I am not getting an error, but my result is null. The picpath looks like this:

/110475388978628/picture

I copied the code directly from here but it isn't working. Any Idea what I'm doing wrong? I have the access token because I am able to get the page ID through the graph request

If you want to get the picture in the same request as the rest of the users information you can do it all in one graph request.

let request = FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, email, picture.type(large)"])
request.startWithCompletionHandler({ (connection, result, error) in
    let info = result as! NSDictionary
    if let imageURL = info.valueForKey("picture")?.valueForKey("data")?.valueForKey("url") as? String {
        //Download image from imageURL
    }
})

there is no parameter called "fields". replace ["fields" : "data"] with nil

let pictureRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: picPath, parameters: nil, HTTPMethod: "GET")
                            pictureRequest.startWithCompletionHandler({ (connection: FBSDKGraphRequestConnection!, result, error) -> Void in
                                if (error != nil) {
                                    print("picResult: \(result)")
                                } else {
                                    print(error!)
                                }
                            })

You can use the Graph API explorer tool to help construct the graph request first: https://developers.facebook.com/tools/explorer

In this case, you'll see that you want the graph path to be just the object id (i.e., your picPath should be just 110475388978628 and your parameters should be [ "fields" : "picture"].

Then you'll want to parse the "url" out of the result["picture"]["data"]["url"].
