DSS boxcarring 和 request_box

Question

我在 DSS boxcarring 中遇到问题。

我在 DSS 中启用了 boxcarring，并为 select 分别从三个表中获取数据编写了查询，并将它们插入到另外三个表中。当我尝试使用它并单击 begin_boxcar 然后我的三个操作然后 end_boxcar 它运行良好。自动创建一个操作 (request_boxcar) 并按顺序包含我的三个操作。当我尝试点击它时，它起作用了，我的操作是运行但是当我使用任务计划和 select request_box 时，我遇到了错误。我在我的浏览器中将它与我的端点一起使用，但它不起作用。我该如何解决？

感谢您报告此问题。这是因为，当它被数据服务任务调用时，它无法检索传入的消息。我创建了一个 JIRA，您可以从 here 找到它。您可以从那里跟踪进度，它将在即将发布的版本中得到修复。
