[Bug]: Login sometime not working on iOS and HTTP Client Error with status code: 500

[FantaMagier]

What happened?

On the latest version of the Flutter OneSignal SDK, I think the login function doesn't work on some devices. The patch request https://api.onesignal.com/apps/APPID/users/by/onesignal_id/ONESIGNALID gets a 500 request on some iOS devices. In the OneSignal dashboard you can see that login sometimes does not work. I think this is related.`

Steps to reproduce?

1. Install latest OneSignal Flutter SDK
2. Use this Code: (I am useing the Qonversion User ID which is working on Android and on some iOS Devices) This ID is a normal String 

Init in main:

OneSignal.Debug.setLogLevel(isTestMode ? OSLogLevel.verbose : OSLogLevel.none);

  OneSignal.consentRequired(true);

  OneSignal.initialize(ID);

In the Func to start the prompt

  await OneSignal.consentGiven(true);
              QUser qonID = await Qonversion.getSharedInstance().userInfo();

              // ignore: unnecessary_string_interpolations
              await OneSignal.login("${qonID.qonversionId.toString()}");

              await OneSignal.Notifications.requestPermission(true);

What did you expect to happen?

The External ID is set correctly and the user don't get a 500 Response Code

@FantaMagier could you share the exact payload from the xcode log that is getting the 500 error? You may have to enable OneSignal verbose logging.

@jkasten2 I got the following logs:

Hi @FantaMagier, it seems your log cut out key information. I see the 200 success response the SDK makes to fetch in app messages from the server. I don't see the 500 error.
