Heroku и Rails - пропущены параметры при отправке в heroku

Question

Задача

У меня есть простая модель, которая требует только поля заголовка. В его контроллере я просто создаю новую модель, используя это поле. Звучит просто, но когда я запускаю его на Heroku и делаю запрос на публикацию с полем заголовка, он не попадает в контроллер. Кажется, это происходит только на Heroku, потому что локально все работает нормально.

Миграция базы данных

class CreateFolders < ActiveRecord::Migration[5.2]
  def change
    create_table :folders do |t|
      t.string :title
      t.belongs_to :user, index: true
      t.timestamps
    end
  end
end

Контроллер

class FoldersController < ApplicationController
  before_action :set_folder, only: [:show, :update, :destroy]

  # GET /folders
  # GET /folders.json
  def index
    @folders = Folder.all
  end

  # GET /folders/1
  # GET /folders/1.json
  def show
  end

  # POST /folders
  # POST /folders.json
  def create
    @folder = Folder.new(folder_params)

    if @folder.save
      render :show, status: :created
    else
      render json: @folder.errors, status: :unprocessable_entity
    end
  end

  # PATCH/PUT /folders/1
  # PATCH/PUT /folders/1.json
  def update
    if @folder.update(folder_params)
      render :show, status: :ok
    else
      render json: @folder.errors, status: :unprocessable_entity
    end
  end

  # DELETE /folders/1
  # DELETE /folders/1.json
  def destroy
    @folder.destroy
  end

  private
    def set_folder
      begin
    @folder = Folder.find(params[:id])
      rescue ActiveRecord::RecordNotFound => e
    render json: {
      error: e.to_s
    }, status: :not_found
      end
    end

    def folder_params
      params.permit(:title).merge(user_id: current_resource_owner.id)
    end
end
