大家好，
我在我的网站上启用了“AI 嵌入语义搜索”，但每当我尝试搜索时，都会出现 500 内部服务器错误，并且没有返回任何结果。当我禁用该设置时，常规搜索功能正常。
以下是我在浏览器控制台中看到的内容：

我还附上了错误的截图。
有人以前遇到过这个问题吗？或者有人知道可能是什么原因造成的/我应该检查哪些内容（设置、API 密钥、日志等）？任何指导都将不胜感激。
提前感谢！

是的，我配置过了。我在 AI 设置页面中配置了一个 Gemini 嵌入模型，并且运行测试按钮成功完成，结果显示为成功！，如截图所示。因此，嵌入模型似乎已正确配置。
此外，顶部还显示了这个错误，我不确定它是否与此有关。

/logs 中可能也包含更多信息，因为 500 类错误会记录在那里。你能检查一下吗？
“成功！”仅确认 API 凭据和端点有效，但并未测试语义搜索过程。

看来我只需要在 Discourse-AI 管理设置中重新创建 Gemini 的 Embeddings 配置，并将嵌入维度设置为 3072 就行了。我猜这个配置是很久以前创建的，当时默认值还是 768。
感谢 @nat 提醒我去查看日志！
