Error message

window.siyuan.languages._kernel[28]

What it means

Fallback error text used by fetchAIEditorSSE when the failed /api/ai/editor/chat response body cannot be parsed as JSON (for example an HTML error page from a proxy). The localized kernel message window.siyuan.languages._kernel[28] is kept as the generic error and thrown after the json() parse fails, because no server-side msg is available.

Solutions

1. Treat the message as generic: the real cause is the HTTP status, not the text
2. Check for proxies or gateways returning non-JSON error bodies between client and kernel
3. Retry after confirming kernel health and AI configuration
