Error: Cannot find module 'globfile?YOPPydNxoo'

[Vehmloewff]

I have set my external modules to be this:

export default {
	// ...
	external = id =>
	(id[0] !== '.' && !nodePath.isAbsolute(id) && id !== `@routes`)
	// ...
}

When I run the app, I get this error.

Error: Cannot find module 'globfile?YOPPydNxoo'

Thrown by this line of code:

var routes = _interopDefault(require('globfile?YOPPydNxoo'));
