使用API​​将数据插入BigQuery到日期分区表

Question

我尝试使用分区将数据插入到BigQuery表中。 我总是得到错误：

"errors": [
         {
            "domain": "global",
            "reason": "internalError",
            "message": "An internal error occurred and the request could not be completed."
         }

当我使用分区创建此表时 - 一切正常。 当我创建一个27列的小桌子 - 一切正常。 但是当我尝试插入更多列时 - 我得到了这个错误。

这是我的架构和我的代码：

有什么可以反映这个错误？如何获得有关此错误的更多详细信息？
