Reason modules using the new component syntax don't work with derivePathFromComponentName

[joaquindk]

This code

let text = ReasonReact.string;

[@react.component]
let make = () => {
  <div>
    <h1> (text("404 Not Found")) </h1>
    <p>
        (text("You just hit a route that doesn't exist... the sadness."))
    </p>
  </div>
};

React.setDisplayName(make, "404");

Will provide the following error when you try to access http://localhost:8000/404:
