ruby-on-rails - Ckeditor error 500 in production

Question

I have the following problem only production with ckeditor gem

ActionView::Template::Error (No input found for ckeditor):
 9:   <% end %>
10:
11:   <div class="inputs clearfix">
12:     <%= f.input :content, as: :ckeditor, input_html: { ckeditor: {toolbar: 'Basic'} }  %>
13:   </div>
14:
15:   <div class="clear-row h10"></div>

I am using SimpleForm, rails, the gem is installed, the rake tasks to copy nodigest assets and this https://github.com/galetahub/ckeditor/issues/91 doesn't work for me
