Model Relationship

I’m new in rails and I’m changing a backend from laravel to rails. My problem is with the inclusion of the data from other model.

I have two models: Questions and User who created the Question. I’ve included the models, controller, and migration of Question and the images about the the bug and the response without the relation expected. The situation is : even establishing the relationships when I use includes the user data is not found by the query even though a query to be correct when a I copy and execute in postgres terminal.

class User < ApplicationRecord

  validates :name, presence: true
  validates :email, presence: true, uniqueness: { case_sensitive: false }, format: { with: /\A([\w+\-]\.?)+@[a-z\d\-]+(\.[a-z]+)*\.[a-z]+\z/, message: I18n.t("errors.models.user.format_email") }
  validates :password, format: { with: /\A(?=.*).{8,72}\z/, message: I18n.t("errors.models.user.format_password") }, if: :password_required?

  before_save :downcase_email!
  after_create :send_confirm_email

  has_many :sessions, dependent: :destroy
  has_many :user_verifications, dependent: :destroy
  has_many :courses
  has_many :questions

class Question < ApplicationRecord
    has_many :replies
    belongs_to :user

    validates :title, presence: true
    validates :category, presence: true
    validates :body, presence: true
    validates :tags, presence: true

   default_scope {includes (:user)}
   scope :with_replies, ->{ includes(:replies)}


class CreateQuestions < ActiveRecord::Migration[6.1]
  def change
    create_table :questions do |t|
      t.references :user, null: false, foreign_key:true, index: true
      t.string :title
      t.string :category
      t.text :body
      t.boolean :solved, default: false
      t.string :tags, array:true, default: []
      t.integer :replies_count, default:0
