Firebase FCM : invalid-argument

Question

我是第一次尝试 FCM，所以只需使用他们的示例代码。事实上，我什至在发送他们的示例消息。以下代码直接来自文档(来自其示例消息传递 android 工具的 token 除外)失败:

exports.onBroadcastCreated =    functions.firestore.document('/apath    /...').onCreate(async event => {
   notification:{
  title:"Portugal vs. Denmark",
  body:"great match!"
},
token: 'eU2YUsi4Ugs:APA91bFH5bR9B1xosqrjvpw7HG4UkYTlDizmtra9pQRge-b4JxRbLjq9PVw91rqZytkUMKJXjPHd_dRlHHMk1bExCo_6Dxv99Vfp8MYz-H16Y9zmG8EFlWXNH4Tw_h6NRj2z1gLcz10m'
};

// Send a message to the device corresponding to the provided
// registration token.
return admin.messaging().send(message)
  .then((response) => {
    // Response is a message ID string.
    console.log('Successfully sent message:', response);
  })
  .catch((error) => {
    console.log('Error sending message:', error);
    console.log(message);
  });

}

如您所见，当创建文档时，通知将从云功能发送。该函数被称为 OK，但日志显示如下:

Answer 1

正如 Carlos Fernandez Sanz 指出的那样，造成这种情况的一个原因是客户端和服务器连接到不同的 Firebase 项目。项目名称出现在 google-services.json 中文件在客户端和服务器上的凭据 json 中。
