DSS boxcarring 和 request_box

Question

我在 DSS boxcarring 中遇到问题。

我在 DSS 中启用了 boxcarring 并编写了查询以分别从三个表中选择数据并将它们插入另外三个表中。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。一个操作（request_boxcar）是自动创建的，并按顺序包含我的三个操作。当我单击它尝试它时，它可以工作并且我的操作已运行但是当我使用任务计划并选择request_box 时遇到错误。我在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修复。
