Redux: ストアにディスパッチされたときにアクションは見られませんでした。

次のコードのReact以外のプロジェクトがあります
。

_index.js_

import configureStore from 'js/store/configureStore'

/* Redux Imports */
import { createPage } from 'js/actions/page'

// Boot the App
document.addEventListener('DOMContentLoaded', function () {
  const initialState = window.__INITIAL_STATE__
  const pageId = window.__INITIAL_STATE__.page
  const store = configureStore(initialState)
  store.dispatch(createPage(pageId))
})

*actions/page.js*
function initPage (pageId) {
  return {
    type: 'CREATE_PAGE',
    page: pageId
  }
}

export function createPage (pageId) {
  return dispatch => {
    dispatch(initPage(pageId))
  }
}

_reducers / page.js_

/**
 * Page Mediators get imported here
 * Page Mediators are brokers that hold page initialization.
 * The bundle includes all page mediators but they will not be activated
 * unless thre reducer calls them.
 */
import * as cart from 'js/templates/cart'

/**
 * This is a edge case, index.js boots the app and we are subscribing to 
 * a Redux @<strong i="11">@INIT</strong> action instead of adding one more layer of actions
 * which leads to unintended scenarios.
 */

const page = (state = {page: []} , action) => {

  console.log(state)
  switch (action.type) {
    case '@<strong i="12">@INIT</strong>':
      console.log('initializing page:' + state.id)
      console.log(state)
      dispatch({type: 'CREATE_PAGE',page: state.id})
      cart.init()
      return state
    case 'CREATE_PAGE':
      console.log('initializing page:' + state.id)
      cart.init()
      return state
    default:
      return state
  }
}
export default page

私が抱えている問題は、 actions/page.jsがCREATE_PAGEアクションを認識しないことです。 何か考えはありますか？
