azure-devops - 运行 WorkItemMigration 时出错：System.InvalidOperationException

Question

我使用azure-devops-migration-tools版本 11.9.20.0。

我正在尝试将 AZDO 项目迁移到 AZDO。

我在源项目上创建了与目标项目相同的方法结构。

但是迁移工作项的过程正在进入一个灾难性的阶段。

这是日志

你能帮我理解为什么这个序列包含多个元素吗？

这个问题在 github 上的这张票中得到了解决。我在这里发布答案。因此，对于遇到相同问题的其他成员轻松找到解决方案将很有帮助。

在配置文件中，语言映射无效：

"LanguageMaps": {
      "AreaPath": "WorkItems-from",
      "IterationPath": "WorkItems-from"

它应该是：

"LanguageMaps": {
  "AreaPath": "Area",
  "IterationPath": "Iteration"

注释掉也不正常// "AuthenticationMode": "Prompt",。
