Hanami: undefined method `size' for nil:NilClass

Question

I keep learning hanami and ran into the following problem: when I initialize and check the parameters, I encounter the following error

Boot Error
Something went wrong while loading /Users/anewaccount/Projects/Mediateka/config.ru

my action:

# frozen_string_literal: true

require 'pry-byebug'
require_relative 'auth_base_action'

module Web
  module Controllers
    module Auth
      class SignUp < AuthBaseAction

        params do
          required(:user).schema do
            required(:first_name).filled(:str?)
            required(:last_name).filled(:str?)
            required(:email).filled(:str?, format?: /@/)
            required(:password).filled(:str?).confirmation
          end
        end

        def call params
          binding.pry
        end
      end
    end
  end
end

I wrote the params block according to the example from the official documentation on the idea that it should work, but I catch NoMethodError: undefined method `size 'for nil: NilClass I also saw in the official documentation that these validations are delegated from Hanami :: Validations, I installed gem' hanami- validation 'according to their official documentation, but I had the same error, then I started looking at other people's code and they were successful using the example from the official documentation. Please tell me what is the error or please explain what am I doing wrong? I'm already very confused
