[Furkan Rehber]

How did you encounter this bug?

Stylelint showed me an error when I opened the SCSS/CSS file and pressed any key.

Stylelint Configuration

module.exports = {
    rules: {
        "function-no-unknown": null,
        "scss/function-no-unknown": true,
    },
};

Actual Behaviour

This is not working properly. When I press any key and activate Stylelint in my SCSS/CSS file, it shows me an error similar to this:
..."message":"ENOENT: no such file or directory, open 'somewhere\index.json'"...

Expected Behaviour

I expect it to work as expected.

I found it myself while searching for the cause of the problem. The folder name must not contain the # character.

#foo/ <---------------- The # character causes an error.
