UPDATE 31.10.: Amazon Alexa - ioBroker Skill läuft aus ?

Hallo zusammen

Ich versuche, über Firebase Push-Nachrichten an meine eigene Smarthome-App zu pushen.
Dazu braucht man OAUTH-Authentification.
Das Ganze funktioniert selten, aber meistens lässt es den Adapter abstürzen.
es verwendet https und googleapis - die sind beide registriert in der Instance.

Wenn ich das Skript direkt auf meinem Server ausführe mit 'node push.js', dann gehts.
Kann es sein, dass der Code zu aufwändig ist für den Adapter?

Es wird ein AccessToken generiert und danach damit die Push-Meldung abgesetzt.
Wie gesagt - selten geht es - zumeist aber nicht.

var registrationToken = 'mytoken';
const https = require('https');

const { google } = require('googleapis');

const PROJECT_ID = 'ff-a78f0';
const HOST = 'fcm.googleapis.com';
const PATH = '/v1/projects/' + PROJECT_ID + '/messages:send';
const MESSAGING_SCOPE = 'https://www.googleapis.com/auth/firebase.messaging';
const SCOPES = [MESSAGING_SCOPE];

/**
 * Get a valid access token.
 */
// [START retrieve_access_token]
function getAccessToken() {
  return new Promise(function(resolve, reject) {

      //// KEY ist JSON-Account-Datei aus firebase
    const key = {
  "type": "x",
  "project_id": "y",
  "private_key_id": "z",
  "private_key": "-----BEGIN PRIVATE KEY-----",
  "client_email": "firebase-adminsdk-86kq0@ff-a78f0.iam.gserviceaccount.com",

}
      const jwtClient = new google.auth.JWT(
      key.client_email,
      null,
      key.private_key,
      SCOPES,
      null
    );
    jwtClient.authorize(function(err, tokens) {
      if (err) {
        reject(err);
        return;
      }
      resolve(tokens.access_token);
    });
  });
}

@dominic-reber Kann ich irgendwie das funktionierende Skript wo hinkopieren und aus dem IoBroker-Javascript-Script starten?
