This does not run. Cloned repo, copy template_config.yaml, and api will not start tested in multiple environments.

No it does not look right. I tried to replicate but it won't work. Can you please git pull? I've added one logging line to narrow down the resource that fails to initialize. And could you post the output?

So this is interesting.

Windows I can't make build and it is pulling plynxteam/backend:latest which is using python:3.7-slim and gives the same error above.

Linux after making using python:3.8-slim:

I added the following to the Dockerfile which seemed to have it up and running.

RUN echo '[]' > /app/nodes.json

Thanks for the feedback! Do I understand it correctly, it worked eventually on Linux but not Windows? Only when you changed base docker image to python:3.8-slim? I should be python:3.8-slim by default.

[ghost]

Windows was pulling from docker registry (because I could not build it) which was using python:3.7-slim. So I think there is incompatibility with 3.7. When I built the image it used 3.8 and worked fine.

We decided to move away from this project as I had many other issues from logging in after creating a user and the lack of documentation.

Thanks
