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

Discovered On Mar 18, 2026

Primary Metric open

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 -" C:\MiroFish-Offline\lib\site-packages\requests\__init__.py:113: RequestsDependencyWarning: urllib3 (2.6.3) or chardet (7.1.0)/charset_normalizer (3.4.6) doesn't match a supported version! warnings.warn( [21:19:28] WARNING: Schema query warning (may already exist): {code: Neo.ClientError.Statement.SyntaxError} {message: Vector indexes are not available on relationships.

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 #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.

Updated with Neo4j to 5.18. Didn't help.

Will investigate more later.

h20lee • Mar 18, 2026

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.
