我尝试部署 function 时出错

Question

我正在尝试部署我的代码，但出现错误

我的索引代码是：

'use strict'

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);


exports.sendNotification = 
functions.database.ref('/Notifications/{receiver_user_id}/{notification_id}')
.onWrite((data, context) =>
{
const receiver_user_id = context.params.receiver_user_id;
const notification_id = context.params.notification_id;

console.log('We have a notification to send to :' , receiver_user_id);

if (!data.after.val())
{
    console.log('A notification has been deleted :' , notification_id);
    return null;
}

const DeviceToken = admin.database().ref(`/Users/${receiver_user_id}/device_token`).once('value');

return DeviceToken.then(result =>
{
    const token_id = result.val();

    const payload =
    {
        notification:
        {
            title: "New Chat Request",
            body: `you have a new Chat Request, Please Check.`,
            icon: "default"
        }
    };

    return admin.messaging().sendToDevice(token_id, payload)
    .then(response =>
        {
            console.log('This was a notification feature.');
        });
});
});

显示的错误是这样的：

npm ERR! code ELIFECYCLE  npm ERR! errno 1

npm ERR! functions@ lint: `eslint .`

npm ERR! Exit status 1

npm ERR!

npm ERR! Failed at the functions@ lint script.

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:

}

您需要在此处捕获错误：

then(response =>
        {
            console.log('This was a notification feature.');
        }).catch(error => handle error here)
