My Ai Agent is not communicating with my Qdrant Vector Store.
When I execute the Qdrant Vector Store step manually I can see that the embeddings Ollama node is read. Unfortunately the Ai agent is not able to access this information.
What could be the issue?
The system prompt in the Ai agent is:
You are a helpful assistant.
Always use the Qdrant vector store tool for refining your answers.
