为什么节点js中的云功能没有正确部署

在这里我使用云功能来创建用户当我尝试部署此代码时，我正在使用快速模块，它部署到云功能，并显示消息：错误：功能未正确部署

const express = require('express');
const functions = require('firebase-functions');
const admin = require('firebase-admin');
const serviceaccount = require('./ServiceAccountKey.json');

const app = express();

admin.initializeApp({
credential: admin.credential.cert(serviceaccount)
});


app.post('/',(req,res)=>{
if(req.method!== 'POST'){
    res.status(400).send("what are u trying baby");
    return;
}
admin.auth().createUser({
    email:req.body.email,
    password: req.body.pass,
}).then(function(userRecord){
    res.send({'uid': userRecord.uid});
    return;
}).catch(function(error){
    res.send({'error': 'Try COrrect one baby'});
    return;
});
return;
});
exports.register = funtions.Https.onRequest(app);

当我在最后添加这个

module.exports = {
app
}

它显示部署的功能，但它没有显示在云功能仪表板中

我在这做什么错

这是我得到的错误我无法得到错误的错误

您的代码从不使用firebase-functions模块来声明云函数。您的functions变量未使用。您不能只导出任何期望它运行的功能 - 它必须由SDK构建。

如果您要部署Express应用程序，则需要通过HTTP类型函数将其导出：

exports.app = functions.https.onRequest(app);
