I'm experiencing the very same issue. Just cloned this boilerplate https://github.com/gkubisa/elm-app-boilerplate

[gothy]

So, I've narrowed the issue to AppRoute.elm in the boilerplate. Experiments brought me to this https://github.com/gkubisa/elm-app-boilerplate/blob/master/elm/App/AppRoute.elm#L50

Renaming the toString function to toStr seems to "fix" the "error". I'm not sure if it's this ticket is a good place to discuss this, but I found it interesting since it relates to the very special toString function...

Hi, thanks a lot for taking the time to debug this! Looks like the problem is that the current regex is not robust enough to handle code not following elm-format rules (for type annotations and function definitions). In the case of AppRoute.elm, there's no space between toString and the succeeding colon. For now, try to format the files first using elm-format (e.g. elm-format src/) before opening them. Will include a fix in the next release. Thanks again!
