Why does an error occur when trying to change the language in the spree application?

Question

Ruby on Rails

Hello, I made a store based on spree commerce, everything went well until I tried to change the default localization, according to the documentation I downloaded the i18n gem, added it to the config/application.rb file, but the server gives an error ActionController::UrlGenerationError in Spree::Home#index , No route matches {:action=>"show", :controller=>"spree/taxons", :id=>nil}, possible unmatched constraints: [:id]config.i18n.default_locale = :ru

<% if taxonomy.root.children.any? %>
        <h4 class='taxonomy-root'><%= Spree.t(:shop_by_taxonomy, taxonomy: taxonomy.name) %></h4>
      <%= taxons_tree(taxonomy.root, @taxon, max_level) %>
      <% end %>
    <% end %>
  <% end %>

If you believe the logs, then the error is in this line <%= taxons_tree(taxonomy.root, @taxon, max_level) %>
Please tell me what is the problem?
