问题是我收到了一些JSON对象，因为我们正在替换所有的$，现在当尝试用相同的对象在mongo DB中相同时得到了错误，因为版本在JSON中是重复的，所以得到了冲突错误。 现在我将尝试修复这个问题，当我们在键的最后一个字符串中获得版本时，它将'.version'替换为'._version'。 需要在ES6中找到最好的方式。 我会尽量避免传统的方法，比如看键等。
// below string was convert with JSON.stringify() output.

const result = JSON.parse((JSON.stringify(twin)).replace(/[$]/g, ''));
return result;
现在返回之前，结果需要替换
twin.properties.reported.version到twin.properties.reported._version
类似的方式，如果我们找到的版本在之间，不需要做任何事情对它。
Twin.Properties.Reported.$Metadata.Version.$LastUpdated到Twin.Properties.Reported.Metadata.Version.LastUpdated
不能用双引号将字符串换行。
这个管用
