Stuck in "Configuration generating，Start polling wait..."

[h20lee]

Anyone encountering the issue at the 3rd step, "Generate Dual Platform Simulation Configuration", it just continue to show polling wait, and the console keeps repeating, "127.0.0.1 - - [18/Mar/2026 21:20:39] "GET /api/simulation/sim_ac281b07ef90/config/realtime HTTP/1.1" 200 -"

Thanks for the report. The core issue is that your graph appears empty (0 nodes, 0 edges) — the simulation config generator can't proceed without graph data.

A few things to check:

1. Did Step 1 (graph building) complete successfully? Check the graph panel — do you see nodes and edges?
2. Is your Ollama embedding model loaded? Run ollama list and confirm you have an embedding model (e.g., nomic-embed-text)
3. The created_at property warning suggests the Neo4j schema may need updating — try running with Neo4j 5.18 (see PR Fix Neo4j version to support relationship vector search (>=5.18) #10)

Can you share:

• Your .env config (redact any API keys)
• Output of ollama list
• Whether Step 1 showed a populated graph

This will help narrow down whether it's a graph build failure or a config generation bug.

Thanks for looking into this. It did per screenshot, however nothing in it.

Step 3
I am going to update this later, and see if it helps.

[h20lee]

Updated with Neo4j to 5.18. Didn't help.

Will investigate more later.

[h20lee]

BTW, instruction on frontpage still mentioned Neojs 5.15, and should be updated to 5.18 for the docker run instruction.

this also is happening to me, i just have some doubts, could it be related to the default ollama service having a really small max token value. Also why qwen2.5 instead of qwen3.5?
Maybe in the yaml file set the context for the compose to launch ollama.

I'm using qwen3. Are you using manual or docker?

[h20lee]

No luck, but could be due to the following line
[2026-03-20 18:04:27] DEBUG [mirofish.api.simulation.prepare_simulation:422] Check result: is_prepared=False, prepare_info={'reason': 'Missing required files', 'missing_files': ['simulation_config.json', 'reddit_profiles.json', 'twitter_profiles.csv'], 'existing_files': ['state.json']}

I've been looking through the code and I think the root cause might be a chain of silent failures:

1. NER extraction (storage/ner_extractor.py:104) — After retries, this returns {"entities": [], "relations": []} instead of raising an error. So the graph build looks successful but the graph ends up empty.

2. Embedding fallback (storage/neo4j_storage.py:204-206) — If Ollama/nomic-embed-text doesn't respond, the code falls back to empty embedding vectors. Nodes get created but can't be found by vector search.

3. No empty-graph check — Nothing validates that the graph actually has nodes/edges before marking the build as successful.

4. Frontend polling — The /api/simulation/{id}/config/realtime endpoint never returns a "failed" status, so the frontend just keeps polling and showing "Configuration generating, Start polling wait..." forever.

I think I have a fix for all four points in my fork, though I haven't been able to test it end-to-end. Happy to open a PR if you're interested.

i try it when i sometime tonight
