Почему вываливается Actions must be plain objects. Use custom middleware for async actions если мидл подключен?

import {
  createStore as createReduxStore,
  applyMiddleware,
} from 'redux'
import thunk from 'redux-thunk'
import {composeWithDevTools} from 'redux-devtools-extension'
import rootReducer from './reducers'
import {configJsonSchema} from '../json-schemas'
import validateConfig from '../app/validate-config'
import {Config} from '../types'

const parseConfig = (jsonConfig: Config): any => {
  return {
    config: jsonConfig,
  }
}

export default function createStore(config: Config): any {
  const initialState = parseConfig(config)
  const checkSchemaResult = validateConfig(
    config,
    configJsonSchema,
  )
  if (checkSchemaResult === true) {
    return createReduxStore(
      rootReducer,
      initialState,
      composeWithDevTools(applyMiddleware(thunk)),
    )
  } else {
    throw checkSchemaResult
  }
}

import 'babel-polyfill'
import * as React from 'react'
import {render} from 'react-dom'
import {Provider} from 'react-redux'
import App from './ui/app'
import createStore from './store/store'

}

export const Component: React.SFC<{config: Config}> = (
  props: any,
