Hi! This is the friendly automated conda-forge-linting service.

I wanted to let you know that I linted all conda-recipes in your PR (recipes/jupyter-syncthing-proxy) and found some lint.

Here's what I've got...

For recipes/jupyter-syncthing-proxy:

• noarch: python recipes are required to have a lower bound on the python version. Typically this means putting python >=3.6 in both host and run but you should check upstream for the package's Python compatibility.
