Firebase Cloud Messaging: Internal error encountered

Question

I'm trying to send push notifications via a Firebase Cloud Function, but getting an internal error.

Error: Internal error encountered.

My function is simple enough:

sendPushNotification.js

const admin = require('firebase-admin');
const messaging = admin.messaging();

module.exports = function(title, deepLink, deviceTokens) {
  var message = {
    notification: {
      title: title
    },
    data: {
      deepLink: deepLink,
    },
    tokens: deviceTokens
  };

  console.log(`Sending notification ${title} with Deep Link ${deepLink} to ${deviceTokens.length} devices`);
  console.log(deviceTokens);

  return messaging.sendMulticast(message).then(response => {
    console.log(`Success: ${response.successCount}, failure: ${response.failureCount}`);

    if (response.failureCount > 0) {
      console.log(response.responses)
    }
  });
}

The weird thing is that sometimes it does work, but maybe one in 10? The other times I get this less-than-helpful error. The APNs Authentication Key is uploaded in the Firebase Console in the project settings. The App Bundle ID is correct. I'm at a loss for what else could be going on.

(Yes, I am giving the function an array of valid deviceTokens.)

None of the other questions on StackOverflow seem to be related to this internal error, the answers on those questions don't apply here.

Hm, now I randomly got the error `Auth error from APNS or Web Push Service Raw server`. There must be _something_ wrong _somewhere_ at least. — Kevin Renskers, Aug 22 '19 at 14:16
After editing the key in the Apple developer site, not changing anything, simply hitting save, that auth error is now gone. Weird. — Kevin Renskers, Aug 22 '19 at 14:22
And now I am getting the same auth error again, after I didn't get an error and a push notification was delivered. — Kevin Renskers, Aug 22 '19 at 14:59
I ended up recreating the key and uploading it again, and it solved itself, if I remember correctly. — Kevin Renskers, Nov 13 '19 at 12:03
I recreated keys like @KevinRenskers and (only) that made it working again. — citykid, Nov 15 '21 at 10:42
