如何防止工作项中的保存异常？
How to prevent Save Exception in Work Items?
版本 8.9.2 - 当我 运行 使用基本 Scrum 流程（使用将 ReflectedWorkItemId 添加到 WIT 的继承流程进行修改）从 Azure DevOps 迁移到 Azure DevOps 时，我观察到一小部分的保存异常work-items 迁移期间。迁移后，我发现创建的空 work-items 没有标题。示例：

我使用以下步骤重现了这个错误：
1. 设置 modified/inherited Scrum 流程 "Migration" 并将 "ReflectedWorkItemId" 添加到两个独立的 Azure DevOps 组织中的适当 WIT
2. 使用 (1) 中配置的迁移过程设置源和目标项目 "Migration test 2"
3. 在标题为 "Test Changing PBI to Task" 的源项目中创建并保存产品待办列表项 WIT
4. 将刚刚创建的 WIT 的类型更改为类型 Task。通过从 "New" 更改为 "To Do" 解决状态字段问题并保存
5. 设置 configuration.json 配置基于默认 ("init") 生成 json w/ 每个视频的典型修改（空场映射等）。启用迭代处理器和 WIT 处理器。修改 WIT 处理器的 QueryBit 以仅排除测试套件和测试计划 WIT。将 ReplayRevisions 设置为 true。
6. 运行 迁移（在 (2) 和 (3) 中创建和修改的 WIT 上）。重现错误：

迁移自：https://github.com/nkdAgility/azure-devops-migration-tools/issues/485
查看文档后，我找到了 VstsSyncMigrator.Engine.Configuration.Processing.WorkItemMigrationConfig 处理器的 SkipToFinalRevisedWorkItemType 配置元素。文档有点神秘，但我尝试将此配置元素设置为 true 并发现它消除了保存异常，导致成功迁移并且没有 blank-titled work-items.
我搜索了所有问题，但没有找到提及 SkipToFinalRevisedWorkItemType 的信息，除了一个包含 configuration.json 列表的已关闭问题。
如果 SkipToFinalRevisedWorkItemType 的预期功能是解决此保存异常，我建议更新文档以指示 work-item 更改的类型在重播修订时将无法保存，除非 SkipToFinalRevisedWorkItemType 设置为 true .理想情况下，将添加导致更多 graceful/informative 异常处理的代码更新，如果不能在重播修订时成功导航 work-item 类型更改的功能。
如果这些选项中的 none 目前是可能的，那么这个问题可以关闭作为名义文档。

我使用以下步骤重现了这个错误：
1. 设置 modified/inherited Scrum 流程 "Migration" 并将 "ReflectedWorkItemId" 添加到两个独立的 Azure DevOps 组织中的适当 WIT
2. 使用 (1) 中配置的迁移过程设置源和目标项目 "Migration test 2"
3. 在标题为 "Test Changing PBI to Task" 的源项目中创建并保存产品待办列表项 WIT
4. 将刚刚创建的 WIT 的类型更改为类型 Task。通过从 "New" 更改为 "To Do" 解决状态字段问题并保存
5. 设置 configuration.json 配置基于默认 ("init") 生成 json w/ 每个视频的典型修改（空场映射等）。启用迭代处理器和 WIT 处理器。修改 WIT 处理器的 QueryBit 以仅排除测试套件和测试计划 WIT。将 ReplayRevisions 设置为 true。
6. 运行 迁移（在 (2) 和 (3) 中创建和修改的 WIT 上）。重现错误：
（会话 ID：6984b357-03ec-401d-ba03-7d43c84c4c6e）
Found 'Custom.ReflectedWorkItemId' in this project, proceeding.

迁移自：https://github.com/nkdAgility/azure-devops-migration-tools/issues/485
查看文档后，我找到了 VstsSyncMigrator.Engine.Configuration.Processing.WorkItemMigrationConfig 处理器的 SkipToFinalRevisedWorkItemType 配置元素。文档有点神秘，但我尝试将此配置元素设置为 true 并发现它消除了保存异常，导致成功迁移并且没有 blank-titled work-items.
我搜索了所有问题，但没有找到提及 SkipToFinalRevisedWorkItemType 的信息，除了一个包含 configuration.json 列表的已关闭问题。
如果 SkipToFinalRevisedWorkItemType 的预期功能是解决此保存异常，我建议更新文档以指示 work-item 更改的类型在重播修订时将无法保存，除非 SkipToFinalRevisedWorkItemType 设置为 true .理想情况下，将添加导致更多 graceful/informative 异常处理的代码更新，如果不能在重播修订时成功导航 work-item 类型更改的功能。
如果这些选项中的 none 目前是可能的，那么这个问题可以关闭作为名义文档。
