Error message

window.siyuan.languages._kernel[28] (or server-provided data.msg/data.message)

What it means

Thrown by fetchAIEditorSSE when the POST to /api/ai/editor/chat either returns a non-2xx status or does not answer with Content-Type text/event-stream. The kernel rejected the AI chat request (auth, configuration, or server-side failure), so the SSE stream cannot be opened. The displayed text is the server-provided data.msg/data.message when the body is JSON, otherwise the localized kernel fallback at window.siyuan.languages._kernel[28].

Solutions

1. Check that the AI provider is configured and the access token is valid in Settings - AI
2. Verify the kernel is running and the endpoint /api/ai/editor/chat returns 200 with an event-stream content type
3. Inspect the JSON body of the failed response; its msg or message field overrides the generic text
4. Reproduce the request with curl to see the raw status code and body
