内容迁移API：导出未完成 - 已添加具有相同密钥的项目 [英] Content Migration API: Export did not complete - An item with the same key has already been added

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？

解决方案

一个非常广泛的错误......可能有多种原因......这可能是由于您的发布审批工作流程导致的此问题 例如审批人 已经批准了内容，但用户试图启动相同的
请求可能会导致此错误。 

我建议您将日志记录级别设置为详细并检查ULS记录有关此错误的更多详细信息。

希望这有帮助......

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?

Sven

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

解决方案

Hi,

Its a very broad error ... It could be various reasons ...it could be due to your publishing approval workflow that is causing  this  for example the approver  would have already approved the content but user is trying to initiate the same request could cause this error. 

I would suggest you set the logging level to Verbose and check the ULS logs for more detailed information about this error.

Hope this helps...
