当用户尝试回复我们的活动时，会弹出一个“未找到”的提示，但回复仍然被收集。我认为没有丢失任何信息。

我无法重现此问题。您能否提供更详细的信息，例如网站上安装的插件列表、网站日志（位于 `https://example.com/logs`）以及错误发生的具体情况？

您好 @putty

感谢您的报告！我们已找到错误原因并提交了修复程序：

> In \`topic\_view\` serializer, only topics that meet the tag containing \`livestream…\` will have corresponding channel. The \`chat\_channel\_id\` of other topics will be \`null\`.
