How can I open an editor from a script in pycharm?

I'm trying to open an editor in the terminal in pycharm, running the script below and am getting the error:

Error opening terminal: unknown.

The EDITOR env var is set to /usr/bin/nano.

The env var is being read correctly in the MVE below.

I can open the editor if I call $EDITOR from the pycharm terminal command line directly.

The script works if called from a new terminal window, either inside or outside of pycharm.

The problem only arises when running it from a run configuration.

import os
import subprocess


def main():
    editor = os.getenv('EDITOR')
    with open('new.txt', 'w+') as tmp:
        subprocess.call([editor, tmp.name])


if __name__ == "__main__":
    main()

I've found a few related questions, but nothing that explains what the problem is.

The answer seems to be to check the [✓] Emulate terminal in output console checkbox in the Run/Debug Configurations window. This doesn't quite produce a functioning terminal session (there are issues with not seeing keyboard inputs after exiting the editor), but it works just well enough for my debugging purposes.
