application.html.erb where line #6 raised: TypeError: Ruby on rails

I'm facing the following error message:

ExecJS::ProgramError in Restaurantes#index Showing C:/rubyProject/vota_prato/app/views/layouts/application.html.erb where >line #6 raised:

TypeError: O objeto não dá suporte para a propriedade ou método Rails.root: C:/rubyProject/vota_prato

Application Trace | Framework Trace | Full Trace app/views/layouts/application.html.erb:6:in >`_app_views_layouts_application_html_erb__971963449_62998908' Request

I fixed it removing the line:

true %>

from my app/views/layouts/application.html.erb file

after I did it, I faced the other problem =(. I created a action destroy at one controller:

class RestaurantesController < ApplicationController
    def destroy
        @restaurante = Restaurante.find(params[:id])
        @restaurante.destroy
        redirect_to(action: "index")
    end

    def index
        @restaurantes = Restaurante.all
    end

    def show
        @restaurante = Restaurante.find(params[:id])
    end
end

and my index.html.rb file:

<h1>Listagem de Restaurantes</h1>

<table>
  <tr>
    <th>ID</th>
    <th>Nome</th>
    <th>Endereço</th>
    <th>Especialidade</th>
  </tr>

<% @restaurantes.each do |restaurante| %>
  <tr>
    <td><%= restaurante.id %></td>
    <td><%= restaurante.nome %></td>
    <td><%= restaurante.endereco %></td>
    <td><%= restaurante.especialidade %></td>
    <td><%= link_to 'Mostrar', action: 'show', id: restaurante %></td>
    <td>--</td>
    <td><%= link_to 'Deletar', {action: 'destroy', id: restaurante},{method: "delete"} %></td>
  </tr>
<% end %>
</table>

when clicked at Deletar link, it executed same action as Show action, I don't know why
