Following Heroku's Python Getting Started tutorial I am hitting an error

When I run:

heroku local web

I get the error:

internal/fs/utils.js:269
    throw err;
    ^

Error: EISDIR: illegal operation on a directory, read

This error is the result of me using .env for my python venv folder

python3.9 -m venv .env --prompt='heroku-getting-started'

Looks like heroku's python-getting-started expects .env to be this

$ cat .env
TIMES=2

I ended up moving the python venv to .venv instead and that error went away
