firebase deploy get error预期的错误将被处理handle-callback-err

如何解决firebase deploy get error预期的错误将被处理handle-callback-err

firebase部署获取错误期望的错误将被处理handle-callback-err

这是我的代码；我想使用Braintree方法，当我编写index.js时，将其上传到firebase。这是错误代码。

mycode

const functions = require('firebase-functions');
const braintree = require('braintree')
const express = require('express')
const cors = require('cors')

// Init app
const app = express();
app.use(cors({origin: true}));

var gateway = braintree.connect({
    environment: braintree.Environment.SandBox,merchantId:"example",//Fill information
    publicKey:"example",privateKey:"example"
});

app.get('/token',(req,response)=>{
    gateway.clientToken.generate({},(err,res)=>{
        if(res)
            response.send(JSON.stringify({error:false,token:res.clientToken}));
        else {
            response.send(JSON.stringify({error:true,errorObj:res,response:res}));
        }
    })
})

app.post('/checkout',response)=>{
    var transactionErrors;
    var amount = req.body.amount;
    var nonce = req.body.payment_method_nonce;

    gateway.transaction.sale({
        amount:amount,paymentMethodNonce:nonce,options:{
            submitForSettlement:true
        }
    },(error,result)=>{
        if(result.success || result.transaction)
        {
            response.send(JSON.stringify(result));
        }
        else {
            transactionErrors = result.errors.deepErrors();
            response.send(JSON.stringify(formatErrors(transactionErrors)))
        }
    });
});

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

错误代码

如何解决这个问题？

我试图删除node_modules并重新安装npm

但仍然错误
