Hi, Thanks for providing information to look into the problem you have faced.

In exception details Invalid device token is from server. Specially in case of apns2: If token(/deviceId) is of invalid length then server throws error with message Expected 32 or 100 byte hex device token but since you are receiving message of invalid token- It should be issue of invalid characters in deviceId. So I would request you to verify once that deviceId is correct/ the same which you intended to pass when the condition meets for PusGateway apns2 type.

[nimda1902]

the token is from firebaseMessaging.getToken(), how could i verify it?

[mohitpubnub]

Seems like It's fcm/gcm token and with ios simulator the method call is happening with PushGateway.apns2argument so for apns2 type, the token is invalid.

[parfeon]

@mohitpubnub it is possible embed Firebase into iOS application and use it's own tokens with Firebase console. It looks like, under the hood Firebase SDK does exchange of actual device token (the one, which usually iOS application use) on Firebase token (which looks similar to the one, which you will get on Android).

@nimda1902 is it possible to show at leats portion of output from firebaseMessaging.getToken()?

[parfeon]

But @mohitpubnub is correct, if there will be FCM-like token (for me it looks like JWT), then you will need to use other type during registration (for FCM).

[nimda1902]

@parfeon , yes it's JWT. fB1ukAscToCON1IJU_vs3X:APA91bF0dJU....
Already change to DeviceInfoPlugin to get unique id, but still got same error.

String deviceId = Platform.isAndroid ? (await deviceInfoPlugin.androidInfo).androidId : (await deviceInfoPlugin.iosInfo).identifierForVendor;

[mohitpubnub]

It doesn't look like hexadecimal. With apns2, valid hexadecimal device-token is expected.

Hi @nimda1902 , were you able to resolve this ? I am getting the same error.

[Anudnya93]

@mohitpubnub How do we resolve it in react native app. Getting same error. I am using Javascript SDK.
