云函数调用startTransaction()引用数据库事务，安装"wx-server-sdk": "^1.7.0，云函数本地调试可以成功调用。
但上传并部署（所有文件）调用则报错，请问什么原因？
{"errorCode":1,"errorMessage":"user code exception caught","stackTrace":"transaction is not defined\nReferenceError: transaction is not defined\n at EventHandler.exports.main [as realHandler] (/var/user/index.js:92:5)\n at \u003canonymous\u003e\n at process._tickCallback (internal/process/next_tick.js:188:7)"}

在db里加入throwOnNotFound: false get没有数据时，就不会报错。我的也报了，但是在另外一个纯云函数里没有。报错的这个云函数是里面包含了很多请求，根据参数来switch到不同的方法里，你的也是这样写的吗？云函数自身的返回结果log和你的一样，但是我catch到的错误如下
{ code: 'SIGN_PARAM_INVALID',
message: 'envname field not exsit in url' }
ReferenceError: transaction is not defined
“transaction is not defined”这个错误是官方demo有问题，const transaction = await db.startTransaction() 放在try的里面，catch里面肯定找不到
这就开始用了。哥们你是先驱啊，应该你来帮别人答疑的。
