What happened

Hi,
I've got some problems importing document for Knowledge Base Build.

I've downloaded the docker compose file from https://raw.githubusercontent.com/OpenSPG/openspg/refs/heads/master/dev/release/docker-compose-west.yml and launch the services with Docker Compose.

In the "Model Configuration" I've added the model Ollama/bge-m3:567m-fp16 (I've tried bge-m3:567m too)

I've create a "New Knowledge Base " with the following
-Chinese name of knowledge base: MyKB
-English name of knowledge base: MyKB
-Knowledge Base Description: Tell me about Solartech
-Whether public: Private
-Knowledge Base Type: Local

Storage Configuration
-database:mykb
-password: ******
-uri: neo4j://release-openspg-neo4j:7687
-user: neo4j
-Vector configuration: Ollama/bge-m3:567m-fp16 (I've tried bge-m3:567m too)
-language: en

Then in the "Knowledge Base Build" I created a Task, and in the "Basic configuration" I uploaded a File with the following text:

SolarTech Innovations, a renewable energy startup headquartered in Berlin, unveiled its latest product 'EcoGrid Battery' during the annual Clean Energy Summit in June 2023. The advanced energy storage system was co-developed with OceanWave Labs, utilizing their marine-based cooling technology. CEO Dr. Helena Weiss confirmed the product will be distributed through GreenHub Stores across Europe starting Q1 2024. Technical specifications reveal the battery integrates patented 'NanoCool' modules, a breakthrough first presented at last year's Berlin Tech Expo. Environmental analysts predict this collaboration could reduce urban carbon emissions by 40% within five years.

After in the "Segment Configuration/Mapping Configuration" I selected:
-Max Segment length:500
-Index Type:table_index (I also tried kag_hybrid_index,atomic_query_index,outline_index,summary_index,chunk_index)

and in the "Extract Configuration/Import Configuration" I selected:
extraction model: Ollama:smollm2:135m (I also tried openthinker:latest and deepseek-chat)

The task completed without any errors but if I view the log in the "Execution Log" section I see the following lines:

But in the "Knowledge Exploration" section I don't see any graphs.

Is there something I'm doing wrong?
Thank you for all.
