内容迁移API：导出未完成 - 已添加具有相同密钥的项目

问题描述

我们正在使用内容迁移API导出和导入spWebs。目前我们收到一些spWebs错误。这来自ULS日志。

内容迁移	开始出口。
内容迁移	[ - 2147024809] [System.ArgumentException] [已添加具有相同密钥的项目。]
内容迁移	导出未完成。

有没有人有一个想法？

Hi,

we are using the Content Migration API to export and import spWebs. Currently we are receiving errors with some spWebs. This comes from the ULS Log.

Content Migration	Starting Export.
Content Migration	[-2147024809] [System.ArgumentException] [An item with the same key has already been added.]
Content Migration	Export did not complete.

Does anyone have an idea?

P.S.: This is the full stack trace:
