服务工作者事件waitUntil()传递了一个拒绝的承诺'TypeError:b为null'

这是我的服务工作者文件,显示推送通知:

importScripts('https://www.gstatic.com/firebasejs/3.5.0/firebase-app.js');
importScripts('https://www.gstatic.com/firebasejs/3.5.0/firebase-messaging.js');

var config = {
    apiKey: "my_key",
    authDomain: "my_domain.firebaseapp.com",
    databaseURL: "https://my_db.firebaseio.com",
    storageBucket: "my_bucket.appspot.com",
    messagingSenderId: "my_sender_id"
};
firebase.initializeApp(config);


var messaging = firebase.messaging();

messaging.setBackgroundMessageHandler(function (payload) {

    var notificationTitle = 'Hello World';
    var notificationOptions = {
        body: 'Test push notification'
    };

    return self.registration.showNotification(notificationTitle,notificationOptions);

});
