Unable to Register IOS device to Mobile First 8

Question

I am able to see the iOS device under devices tab in MF, registered to my application. but pushing a notification fails with the below error:

An error occurred while the notification was sent. Internal server error. No devices found.

Upon reviewing IOS code, I noticed the below issue while invoking MFPPush.sharedInstance.registerDevice(nil)

Cannot retrieve a valid authorization header for header. Check resource and authorization server configuration.

I am using the code from the git sample. Below is the snippet throwing the error:

 @IBAction func registerDevice(_ sender: AnyObject) {
        print("Attempting Device registration with Mobile First")
        WLAuthorizationManager.sharedInstance().obtainAccessToken(forScope: "push.mobileclient") { (token, error) -> Void in
            if (error != nil) {
                print("Did not recieve an access token from server: " + error.debugDescription)
            } else {
                WLClient.sharedInstance()?.setDeviceDisplayName("White Ipad", withCompletionHandler: { (error) in
                    if error == nil{
                        print("device display name is set")
                    }else{
                        print("error setting device name: " + error.debugDescription)
                    }
                })
                print("Recieved the following access token value: " + (token?.value ?? "no token"))
                MFPPush.sharedInstance().registerDevice(nil) { (response, error) -> Void in
                    if error == nil {
                        self.enableButtons()
                        self.showAlert("Registered successfully with Mobile First")
                        print(response?.description ?? "")
                    } else {
                        self.showAlert("Registration failed with Mobile First.  Error \(error?.localizedDescription)")
                        print(error?.localizedDescription ?? "")
                    }
                }
            }
        }
}

Mobile First Config: I have followed the documentation and configured the UserLogin security check from the sample git project and have removed scope to push.mobileclient under security.

Reading the OAuth Security in MF, i understand the that token is necessary to access resources, but I am unable to figure out how to attach the token in registerDevice().

It seems to be you haven't configured Push Notifications properly in MobileFirst Server.

• Make sure that you have added push.mobileclient scope in Security tab of your application. If you are not using any security check, you can add scope like below.

• Check whether your application is configured valid iOS provisioning profile enabled with Push Capability

• Make sure that you have uploaded valid sandbox/production certificates in Push tab of your particular app in MFP Operations Console. More details : here

• Make sure your app is enabled Push Capability in the project setting and also check you sending device token to MF Server using MFPPush.sharedInstance().sendDeviceToken(deviceToken) API in didRegisterForRemoteNotificationsWithDeviceToken method of AppDelegate file
