在Hello World应用程序中使用无效JSON的Cloud Functions 400 Bad Request

Question

我有一个hello world cloud功能应用程序，它可以通过 firebase服务在本地运行，也可以在 firebase部署

后在线运行

const functions = require('firebase-functions');

exports.helloWorld = functions.https.onRequest((request, response) => {
 response.send("Hello from Firebase!");
});

我可以在本地打开http://localhost:5000/testing-98b0b/us-central1/helloWorld，没有任何问题，但是如果我使用邮递员发送带有无效主体（如“＃”）的帖子，则会崩溃并继续加载并显示以下错误：

error: { SyntaxError: Unexpected token # in JSON at position 0
    at JSON.parse (<anonymous>)
    at createStrictSyntaxError (/usr/local/lib/node_modules/firebase-tools/node_modules/body-parser/lib/types/json.js:158:10)
    at parse (/usr/local/lib/node_modules/firebase-tools/node_modules/body-parser/lib/types/json.js:83:15)

  expose: true,
  statusCode: 400,
  status: 400,

  type: 'entity.parse.failed' }

在 firebase部署之后，我也可以打开 https://us-central1-staff-testing-98b0b.cloudfunctions.net/helloWorld 没有任何问题，但是如果我使用邮递员发送带有无效主体（如“＃”）的帖子，则会崩溃并返回400错误的请求，并出现以下错误：

    at endReadableNT (_stream_readable.js:974:12)

firebase-functions库中是否存在bug？有什么方法可以处理这种无效请求？
