Facebook App Invite not working

I'm trying to add facebook App Invite like this:

let content:FBSDKAppInviteContent = FBSDKAppInviteContent()         content.appLinkURL = URL(string: "https://fb.me/...")         content.appInvitePreviewImageURL = URL(string: "http://...")          let dialog = FBSDKAppInviteDialog()         dialog.content = content         dialog.delegate = self         dialog.fromViewController = self         dialog.show() 

Relevant Info.plist keys:

<key>FacebookAppID</key> <string>...</string> <key>FacebookDisplayName</key> <string>Blanket</string> <key>LSApplicationQueriesSchemes</key> <array>     <string>fbapi</string>     <string>fbapi20130214</string>     <string>fbapi20130410</string>     <string>fbapi20130702</string>     <string>fbapi20131010</string>     <string>fbapi20131219</string>     <string>fbapi20140410</string>     <string>fbapi20140116</string>     <string>fbapi20150313</string>     <string>fbapi20150629</string>     <string>fbapi20160328</string>     <string>fbauth</string>     <string>fbauth2</string>     <string>fb-messenger-api20140430</string>     <string>fb-messenger-platform-20150128</string>     <string>fb-messenger-platform-20150218</string>     <string>fb-messenger-platform-20150305</string>     <string>fbapi</string>     <string>fb-messenger-api</string>     <string>fbauth2</string>     <string>fbshareextension</string> </array>  <key>CFBundleURLTypes</key> <array>     <dict>         <key>CFBundleURLName</key>         <string>com.my.app</string>         <key>CFBundleURLSchemes</key>         <array>             <string>fb...</string>             <string>myappscheme</string>         </array>     </dict> </array> 

When I run the code, safari window is opened, and closed after showing loading spinner.

This error is returned:

"Error: Optional(Error Domain=com.facebook.sdk.core Code=2 \"(null)\" UserInfo={com.facebook.sdk:FBSDKErrorDeveloperMessageKey=Invalid method_results., com.facebook.sdk:FBSDKErrorArgumentNameKey=method_results})"

Facebook app is installed on the device, and share dialog opens in facebook app.

When i try to debug, in [FBSDKApplicationDelegate _handleBridgeAPIResponseURL:sourceApplication:] response URL is fb...://bridge/appinvites?version=web&bridge_args=%7B%22app_name%22%3A%22...%22%2C%22action_id%22%3A%...%22%7D&error=%7B%22error%22%3A%22server_error%22%2C%22error_description%22%3A%22Error%20retrieving%20application%20configuration.%22%7D

relevant error:

{"error":"server_error","error_description":"Error retrieving application configuration."} 

I'm not sure what that error means, is facebook application config wrong, or iOS application.

The same invite works on Android, iOS app is published, and has valid iTunes URL configured.

I was able to invite friends based on the above code so please check the facebook app id and see whether it is entered correctly. And see whether you have provided the correct url identifier and url scheme in the p list.
