Azure Bot添加至Microsoft Teams后返回"机器人不在对话名单中"错误排查

我们基于Azure Bot在Microsoft Teams中开发了消息扩展功能，用户通过团队频道的对话入口使用该服务。流程如下：接收用户在消息扩展中输入的搜索关键词，在数据库中匹配对应条目，用户选中条目后，自动在团队频道发布指向目标资源的链接消息。

该功能在QA、预发布等测试环境均正常运行，但生产环境出现以下异常：

• 部分搜索关键词能返回预期的「未找到内容」响应
• 多数搜索关键词触发502错误，Bot日志显示错误信息：The bot is not part of the conversation roster

我们通过侧加载（sideloading）方式部署Bot及关联的Teams应用清单，经核对，生产环境与其他环境的Bot及应用配置完全一致。

已查阅Stack Overflow及Microsoft PowerUsers论坛相关内容，多数建议需在Azure中将Bot添加至Teams，此操作已完成，但生产环境问题仍未解决。

以下为应用清单文件（其中引用了已发布至AppSource的eduMe应用）：
