[Solidus 3.2.2] Hello, I'm trying to add a clone route to a controller like for the Admin::ProductsController

clone_admin_product    POST  /admin/products/:id/clone(.:format)  spree/admin/products#clone

config/route.rb

namespace :admin do
    resources :kits
    post 'kits/:id/clone', to: 'kits#clone'
  end

but I get `action_dispatch/routing/route_set.rb588in

add_route': Invalid route name, already in use: 'admin'  (ArgumentError)

Are you defining the routes into a

Spree::Core::Engine.routes.draw do

block?

Yes

Spree::Core::Engine.routes.draw do
  ...
  namespace :admin do
    resources :kits
    post 'kits/:id/clone', to: 'kits#clone'
  end
  ...
end

The error come just when a add the

post 'kits/:id/clone, to: 'kits#clone'

line

resources :kits

alone works?

Yes it's working alone

can you please share the full

routes.rb

file?

Yes ;)

# frozen_string_literal: true

Rails.application.routes.draw do
  # This line mounts Solidus's routes at the root of your application.
  # This means, any requests to URLs such as /products, will go to Spree::ProductsController.
  # If you would like to change where this engine is mounted, simply change the :at option to something different.
  #
  # We ask that you don't use the :as option here, as Solidus relies on it being the default of "spree"
