Failed to generate query

[Fernandez-APU]

This is the command used after cloning the repo in vscode which runs in window:

1. uv venv --python 3.11
2. .venv\Scripts\activate
3. uv pip install -e .
4. uv pip install langgraph-cli[inmem]
5. cp .env.example .env
6. uv run langgraph dev

.env file:

The generate query does not work.

The terminal shows logging error.
