Manual Test Results - Fix Verified

Tested locally with Ollama (gemma3:12b) + Qdrant local storage.

Test 1: Normal mode (list) via Chat SSE

Query: "what are the best sci-fi movies" with mode=list

Result: 1 result returned ("A Matter of Life and Death", score 78), conversation stored successfully.

{
  "user_id": "test-user-123",
  "query": "what are the best sci-fi movies",
  "conversation_id": "conv_test1770362590",
  "summary": "The query about best sci-fi movies yielded a single, highly-regarded film: A Matter of Life and Death...",
  "main_topics": ["British cinema", "World War II", "Fantasy", "Romance"],
  "response_items": 1,
  "response_names": ["A Matter of Life and Death"]
}

No errors. storeConversationExchange completed without 'str' object has no attribute 'get'.

Test 2: Summarize mode via Chat SSE

Query: "tell me about classic sci-fi movies" with mode=summarize

Result: 2 results returned + LLM-generated summary. Conversation stored successfully.

{
  "user_id": "test-user-456",
  "query": "tell me about classic sci-fi movies",
  "conversation_id": "conv_summ1770362649",
  "summary": "Classic sci-fi movies include \"A Matter of Life and Death\" (1946)... and \"Manhunt of Mystery Island\" (1945)...",
  "response_items": 2,
  "response_names": ["A Matter of Life and Death", "Manhunt of Mystery Island"]
}

No errors. The summarize mode handler.summary (a plain string) is now handled correctly without calling .get() on it.

Conversation Storage Proof

2 conversations successfully stored in Qdrant (data/conversations_db/nlweb_conversations):

Error Check

grep "Error storing conversation" server.log → 0 matches
grep "'str' object has no attribute 'get'" server.log → 0 matches

The fix correctly uses handler.final_ranked_answers instead of the removed handler.return_value['content'], and handles summarize mode by using handler.summary directly as a string.
