elm-live crash when a file is not found instead responding with a 404

[lucamug]

If you try an url for a non existing file, for example: http://localhost:8000/xyz/index.html

elm-live will stop with the error:

internal/fs/utils.js:537
    throw new ERR_INVALID_ARG_TYPE(propName, ['string', 'Buffer', 'URL'], path);
    ^
TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string or an instance of Buffer or URL. Received undefined

I can confirm this issue. I saw it after checking a fresh repo and freshly installing elm-live. I guess it was trying to load the index before it was fully built

elm-live --version
4.0.2

git:(master) elm-live src/Main.elm --open

elm-live:
  Server has been started! Server details below:

Anyone have a fork with this fixed? Been dealing with this same issue as well.

At work we use elm-go, a clone that we made to fix some issues of elm-live

This occurs when the index.html file is missing from the --dir
