Relative paths passed as file return undefined

[bencodezen]

After trying to follow the README, this is what I have

// Sync
const sass = require('sass-thematic');

var ast = sass.parseASTSync({
    file: `./test.scss`
});

However, on runtime, I'm getting:

throw new TypeError('Path must be a string. Received ' + inspect(path));

TypeError: Path must be a string. Received undefined

It works if I hardcode the entire file path, but it seems like something is wrong with how the Path is being converted. I'm on Node v6.2.1 and this seems to be a pretty universal problem with a number of different plugins.

I stumbled on the same problem. This one-liner fix is what is needed:
