            Comparing equality between `ActionController::Parameters` and a
            `Hash` is deprecated and will be removed in Rails 7.2. Please only do
            comparisons between instances of `ActionController::Parameters`. If
            you need to compare to a hash, first convert it using
            `ActionController::Parameters#new`.
            To disable the deprecated behavior set
            `Rails.application.config.action_controller.allow_deprecated_parameters_hash_equality = false`.
