Question

我正在尝试使用QuickBooks .NET REST API v2库创建客户。在调用dataservice对象的Add（）方法来提交请求时，我收到一条我不理解的错误消息：

"EntityManager must be access within a transaction"

Google搜索错误消息会对Java产生一些点击，但没有一个看起来真的解决了这个问题，也没有在Intuit-Partner-Platform文档中找到有关该消息的任何文档。

using Intuit.Ipp.Data.Qbd;

            OAuthRequestValidator oauthValidator = new OAuthRequestValidator(accessToken, accessTokenSecret, Constants.CONSUMER_KEY, Constants.CONSUMER_SECRET);
            ServiceContext context = new ServiceContext(oauthValidator, Constants.APP_TOKEN, realmID, IntuitServicesType.QBD);
            DataServices dataServices = new DataServices(context);


            var writeCust = new Customer()
            {
                Name = "Carlos Verdona",
                TypeOf = partyType.Person,
