devise is not creating a new user.

I fill out the sign-up form for a new registration and then when I click on the validate button it redirects me to my sign-in form with this message:

"You need to sign in or sign up before continuing."

When I type User.last in the Rails console, it confirms that the user has not been created.

I can still connect by filling out the sign-in form with the information I have created in my seeds.

User model:

class User < ApplicationRecord
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable, :trackable and :omniauthable
  devise :database_authenticatable, :registerable,
  :recoverable, :rememberable, :validatable

  has_many :biens, dependent: :destroy
  has_one_attached :avatar


  def profile_picture
    if avatar.attached?
      avatar.key
    else
      "default_profile_pic_xl837y"
    end
  end
end

Routes.rb:

  devise_for :users

  resources :biens do
    collection do
      get :userbiens
    end
  end
end
