iOS: Invalid registration token. Check the token format

Question

I am new for Firebase as well as for iOS. I am trying to send push notification using FCM.

I registered an iOS app on FCM. Both .p12 certificates added. Code developed according to FCM.

While sending notification through the Firebase Console, I'm getting the error Invalid registration token. Check the token format.. I don't what mistake I did.

FCM Console

I followed [this](https://firebase.google.com/docs/cloud-messaging/ios/client) tutorial — Shreejay Pendse, Dec 28 '16 at 14:06
@ShreejayPendse i am facing same error.how you solve issue.and what i have to add in single device.device token? — Krutarth Patel, Dec 31 '16 at 11:18
I was facing the same error getting `instanceId` instead of `token`. Just mixed things up. Ensure you are getting exactly token — YTerle, Jan 26 '17 at 14:05

There are two tokens you get at iOS side

Token generated by iOS which is received in method didRegisterForRemoteNotificationsWithDeviceToken
Token generated by Firebase FIRInstanceID.instanceID().token() (this you can print in AppDelegate)

The issue you are facing is because firebase console portal requires token received by way 2 and you are using token received by way 1.

FIRInstanceID.instanceID().token() has now changed to InstanceID.instanceID().token() – Droid Chris May 30 '18 at 20:54

To solve the this issue

I followed complete tutorial of FCM provided for iOS. But while testing or implementing I used APN Server. While using APN Server you need only .pem file

For reference this is my .py file code

import random
from apns import APNs, Frame, Payload

sound = "default"
badge = None
alert = "Message"
identifier = random.getrandbits(32)

apns_enhanced = APNs(use_sandbox=True, cert_file='vendor.pem', enhanced=True)
payload = Payload(alert=alert, sound=sound, badge = badge)
apns_enhanced.gateway_server.send_notification(token_hex_office, payload, identifier=identifier)
apns_enhanced.gateway_server.force_close()

Thanks
