在使用调用数据库事务API时，一直返回SDKError.
测试代码
错误信息
index.js:37 transaction error CloudSDKError: errCode: -1 unknown error | errMsg: collection.add:fail Error:
400 Bad Request

给下详细信息 appId, envId 这些? 应该需要升级
升级了一下开发者工具，提示了更多的错误信息，看起来像是mongo数据库版本问题... MongoDB 4.0里也写了同样一句multi-document transactions are not available for sharded cluster
:(
