Hi,

I followed the instructions given in this playbook. I was able to see the knowledge graph being built and could access the 2D/3D interactive section. However, the RAG search section fails with the error “Error: Sentence transformer service is not available” when I submit a text query.

Here’s my docker ps output:

So, I tried to regenerate the embeddings, but this time the processing failed for some of the documents:

Could you please guide me on the next steps or ways to debug this?

Thanks in advance!

@sbhavani I understand you’re one of the developers on this playbook. Could you please take a look at this issue? I really appreciate your time and help!

Hi ms6174,

Based on your docker ps output, it looks like you’re missing the qdrant container and the compose-sentence-transformers containers. You can get those running with the other services by running:

./start.sh --vector-search

instead of ./start.sh alone.

Please let me know if that works for you, and/or if you have any other questions.
