I am running into the same error--tried both the source method (running the app on the OS directly using python -m cli.main) and the docker version as well with the same issue.

I figured out what the problem is. I had not pinned the python version for this project. It requires python 3.13 or lower for the latest build. Hope this helps someone.

Hi, thanks for the reply! Can you tell me what you specifically did to make it work?

I am running the project as is from the repo

• pyproject.toml requires python>=3.10
• Dockerfile uses python:3.13-slim

[SonnyRajagopalan]

The basic issue is that you likely have a python version that will not work with this project (because the dependencies in pyproject.toml won't be satisfied with the python version). I am using uv for package management, and here's how I fixed it:

uv python pin 3.13
uv sync
source .venv/bin/activate
python -m cli.main

Hope that helps.
