fix(chat): align a2ui assistant ID with deployed graph name#117
Merged
Conversation
The generative-ui system prompt instructed the LLM to produce JSON specs with a "rootKey" field, but the @json-render/core Spec type expects "root". RenderSpecComponent checks `spec()?.root` (line 50), so all LLM-generated specs silently failed to render. Fix: replace all occurrences of "rootKey" with "root" in the prompt. Updated both the source and the streaming deployment copy. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The a2ui Angular app used assistant ID 'c-a2ui' but the production /api proxy routes to the streaming LangGraph deployment, which registers the a2ui graph as 'a2ui_form'. This caused HTTP 422 "Invalid assistant" errors. Fix: update both environment files to use 'a2ui_form'. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

PR #117 changed the a2ui assistant ID from 'c-a2ui' to 'a2ui_form', but the production proxy (examples-middleware.ts) routes chat/a2ui requests to the standalone c-a2ui LangGraph deployment, whose langgraph.json registers the graph as 'c-a2ui'. Revert to 'c-a2ui' to match the deployed backend. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
