Unexpected key "offline" found in previous state received by the reducer. Expected to find one of the known reducer keys instead...

Ah, my apologies! It's actually the same config that fixed #57:

// @flow
import { applyMiddleware, createStore, compose } from 'redux'
import { createEpicMiddleware } from 'redux-observable'
import thunk from 'redux-thunk'
import promiseMiddleware from 'redux-promise-middleware'
import { routerMiddleware } from 'react-router-redux'
import { offline } from 'redux-offline'
import offlineConfig from 'redux-offline/lib/defaults'
import { devToolsEnhancer } from 'redux-devtools-extension/logOnlyInProduction'
import rootEpic from './epics'
import rootReducer from './modules'


function configureStore (
  preloadedState: Object, history: Object,
): Object {

  const epicMiddleware = createEpicMiddleware(rootEpic)

  const middleware = [
    epicMiddleware,
    thunk,
    promiseMiddleware(),
    routerMiddleware(history),
  ]

  // https://github.com/zalmoxisus/redux-devtools-extension
  // https://medium.com/@zalmoxis/using-redux-devtools-in-production-4c5b56c5600f

  const enhancer = compose(  // <-- CHANGED
    applyMiddleware(...middleware),
    devToolsEnhancer(),  // <-- CHANGED
    offline(offlineConfig)
  )

  const store = createStore(rootReducer, preloadedState, enhancer)

  return store

}


export default configureStore

Also, this is my combineReducers():

// @flow
import { combineReducers } from 'redux'
import { routerReducer as routing } from 'react-router-redux'
import { reducer as form } from 'redux-form'

import env from './env'
import request from './request'
import init from './init'
import auth from './auth'

// Examples
import profile from './profile'
import todos from './todos'


const rootReducer = combineReducers({
  env,
  request,
  init,
  auth,

  // Examples
  profile,
  todos,

  // redux-form
  form,
  // react-router-redux
  routing,
})


export default rootReducer

@tribou can you please show how you configure the Redux store, along with and redux-offline configurations.

[lifeiscontent]

@jevakallio any updates on this?

[guilhermebruzzi]

@jevakallio @tribou Have you guys managed to do a workaround? My configuration looks like the one @tribou posted and I'm getting: Cannot read property 'outbox' of undefined
