Breadcrumb not found with name even have unnamed-route-exception

I have an web app with Laravel 5.4 with http://ift.tt/2wxuTRC

My problem is that even I have in my config\breadcrumbs.php

 return [

    'view' => 'partials.breadcrumbs',
    'missing-route-bound-breadcrumb-exception' => false,
    'unnamed-route-exception' => false

];

and in my masterLayout I have:

Breadcrumbs::generate()

I have this error when I try to access a page without name route:

Breadcrumb not found with name ""
