Microsoft Teams BotBuilder——当团队 ID 以 `thread.skype` 结尾时，频道列表为空

Question

我在两个不同的团队中安装了一个机器人。当我为ID以

TeamsInfo.getTeamChannels

结尾的团队做

thread.tacv2

时，我成功获取了频道列表。当我为 ID 以

thread.skype

结尾的团队运行相同的代码时，我收到一个空列表。

完整代码：

package com.mytest;

        "19:***@thread.skype", "***");
    conversation.setConversationType("channel");
    conversation.setTenantId("***");

        installationReference.getConversation().getId());
    List<ChannelInfo> channels = cf.get();
    System.out.println(channels.size()); // 0 for the `thread.skype` team and non-zero for the `thread.tacv2` team
  }

  public TurnContext getTurnContextForConversationReference(ConversationReference cr)
      {
