firebase_admin.exceptions.InvalidArgumentError：注册令牌不是有效的FCM注册令牌

如何解决firebase_admin.exceptions.InvalidArgumentError：注册令牌不是有效的FCM注册令牌

我正在通过Web应用程序通过仓库发送fcm警报。

firebase_admin.exceptions.InvalidArgumentError: The registration token is not a valid FCM registration token

但是我一直收到这种错误。

def send_pushserver():
    # This registration token comes from the client FCM SDKs.
    registration_token = 'KEY'
    # See documentation on defining a message payload.
    message = messaging.Message(
    notification=messaging.Notification(
        title='Hi',body='Message',),token=registration_token,)
    response = messaging.send(message)
    # Response is a message ID string.
    print('Successfully sent message:',response)

发送通知的代码部分。 “ registration_token”包含Web推送证书的密钥对。

我正在上传html文件，以防万一我弄错了部分。

<html>
<div class="demo-layout mdl-layout mdl-js-layout mdl-layout--fixed-header">
    <main class="mdl-layout__content mdl-color--grey-200">
        <div class="mdl-cell mdl-cell--12-col mdl-cell--12-col-tablet mdl-grid">
            <div class="mdl-card mdl-shadow--2dp mdl-cell mdl-cell--12-col mdl-cell--12-col-tablet mdl-cell--12-col-desktop">
                <div id="messages">
                </div>
            </div>
        </div>
    </main>
</div>

<script>
    importScripts('https://www.gstatic.com/firebasejs/8.0.0/firebase-app.js')
    importScripts('https://www.gstatic.com/firebasejs/8.0.0/firebase-analytics.js')
  // Your web app's Firebase configuration
  // For Firebase JS SDK v7.20.0 and later,measurementId is optional
  var firebaseConfig = {
    apiKey: "",authDomain: "",databaseURL: "",projectId: "",storageBucket: "",messagingSenderId: "",appId: "",measurementId: ""
  };
  // Initialize Firebase
  firebase.initializeApp(firebaseConfig);
  //firebase.analytics();
  const messaging = firebase.messaging();
  messaging.onMessage((payload) => {
  console.log('Message received. ',payload);
  appendMessage(payload);
  });

  function appendMessage(payload) {
    showToken(payload);
    const messagesElement = document.querySelector('#messages');
    const dataHeaderElement = document.createElement('h5');
    const dataElement = document.createElement('pre');
    dataElement.style = 'overflow-x:hidden;';
    dataHeaderElement.textContent = 'Received message:';
    dataElement.textContent = JSON.stringify(payload,null,2);
    messagesElement.appendChild(dataHeaderElement);
    messagesElement.appendChild(dataElement);
  }
  
  </script>

</html>

FirebaseConfig是对内容的部分擦除。
