TypeError: Path must be a string. Received undefined

When using Webpack 2.

See the original issue for the explanation and my workaround: https://github.com/jtangelder/sass-loader/issues/298

path.js:7
    throw new TypeError('Path must be a string. Received ' + inspect(path));
    ^

TypeError: Path must be a string. Received undefined
    at assertPath (path.js:7:11)

Ok, I won’t provide a sample repo but other people coming from google can. This issue is not just mine though, you can see at least 2 other people in the linked issue having the same error.
