Why can't Facebook display the map when sharing opengraph ios?

Question

Facebook

Actually I'm trying to share a post using a map via facebook.
in the application settings I did the following

In the object type I created an additional field for geolocation

In the actual object I create

var properties:NSDictionary = ["og:type": "myplanetnamespace:plan", "og:title": "Share on Facebook выа", "og:description": "In the frozen wastes to the north of Winterfell, sinister and supernatural forces are mustering.",
           "myplanetnamespace:geoplace:latitude": String(stringInterpolationSegment: self.plan.venue!.location.latitude),
           "myplanetnamespace:geoplace:longitude": String(stringInterpolationSegment: self.plan.venue!.location.longitude) ]
        var object:FBSDKShareOpenGraphObject = FBSDKShareOpenGraphObject(properties: properties as [NSObject : AnyObject])

Next I create an Action

var action = FBSDKShareOpenGraphAction()
    action.actionType = "myplanetnamespace:create_plan"
     action.setObject(object, forKey: "plan")

Own content

var content:FBSDKShareOpenGraphContent = FBSDKShareOpenGraphContent()
    content.action = action
    content.previewPropertyName = "plan"

Well, I'm starting to fumble

var shareDialog = FBSDKShareDialog()
        shareDialog.fromViewController = self
        shareDialog.shareContent = content
        if ( shareDialog.canShow() == true ){
            shareDialog.show()
        }
        var error:NSError?
        if(!shareDialog.validateWithError(&error)){
            print ("error")
        }

In the settings, I specifically made the field with the location mandatory so that in case of empty filling it would give an error. Actually now it does not give them out, but when sharing in the post, there is still no map with the location. If you shove a picture, then everything is fine.
What am I doing wrong?

Unfortunately, I did not work with this api, so I don’t know how useful my advice will be.
