uninitialized constant Formtastic::I18n::SCOPES

Rails 6.0.1, Puma 4.3.0, Devise 4.7.1, ActiveAdmin 2.4.0, Formtastic 3.1.5

---

Once again I am creating a Rails application. Created the foundation. A couple of models. Made a simple front-end for them. Next install Devise, ActiveAdmin.

In general, nothing unusual. Locally everything works fine.

But on the server, some kind of nonsense began to happen with ActiveAdmin.

In general, the application on the server is working fine. Through the console, I can create all the data. These data are successfully displayed on the site.

But if I go into ActiveAdmin...

Dashboard page displayed successfully. But if I go to the index page of any entity, then I will get the following error (from the log):

The entire log: https://pastebin.com/raw/buWSveBZ

Only one section for entities works - this is the show action. Only two actions for entities work - these are show and destroy. Everyone else catches the error that I showed above.

I absolutely don't understand what's the matter.

I successfully use the identical config/initializers/active_admin.rb file in two other Rails 6 applications. Below I will show an example of one of the file for ActiveAdmin:

# frozen_string_literal: true

ActiveAdmin.register User do
  menu priority: 5

  permit_params :email, :full_name, :roles, :password, :password_confirmation

  remove_filter :users_roles

  controller do
    def find_resource
      scoped_collection.find_by!(pkey: params[:id])
    end
  end

  index do
    selectable_column
    id_column
    column :pkey
    column :email
    column :full_name
    column :roles
    column :current_sign_in_at
    column :sign_in_count
    column :created_at
    actions
  end

  form do |f|
    f.inputs do
      f.input :email
      f.input :full_name
      f.input :roles
      f.input :password
      f.input :password_confirmation
    end
    f.actions
  end
end

I'm hope for your help.

I added this line to all files:

config.filters = false

And this partially solved the problem. Now I can see the index page. But I can't add anything:

If necessary, I can invite an ActiveAdmin team member to my project repository.

If I delete this code:

form do |f|
  f.inputs do
    f.input :title
    f.input :code
    f.input :link
  end
  f.actions
end

I still can't add anything.

Now in the logs it will be:

In the console on the server. In the container of the running application.

Formtastic::I18n::SCOPES
=> ["%{model}.%{nested_model}.%{action}.%{attribute}", "%{model}.%{nested_model}.%{attribute}", "%{nested_model}.%{action}.%{attribute}", "%{nested_model}.%{attribute}", "%{model}.%{action}.%{attribute}", "%{model}.%{attribute}", "%{attribute}"]

[afuno]

Can someone explain to me what it was?

I added these puts:

controller do
  puts
  puts
  puts Formtastic::I18n.inspect
  puts Formtastic::I18n::SCOPES.inspect
  puts
  puts

  def find_resource
    scoped_collection.find_by!(code: params[:id])
  end
end

That is, initially the controller was like this:

controller do
  def find_resource
    scoped_collection.find_by!(code: params[:id])
  end
end

And there is no more problem! What the hell is this? :D
I didn't do anything. Just added puts with the output of the constant SCOPES.

In the next deployment I deleted these puts. And the error reappears!
