Typescript issue along with Redux 4.0.5

[saikats5]

I am getting below errors after upgrading to redux 4.0.5

app/store/reducer.ts:58:7 - error TS2345: Argument of type 'AnyAction' is not assignable to parameter of type 'never'.

58 action
~~~~~~

app/store/reducer.ts:62:18 - error TS2345: Argument of type 'StateRoot' is not assignable to parameter of type 'CombinedState<{ [x: string]: unknown; }>'.
Type 'StateRoot' is not assignable to type '{ [x: string]: unknown; }'.
Index signature is missing in type 'StateRoot'.

62 return reducer(state, action)
~~~~~

Found 2 errors.

Without any code examples, I can't tell what's going on here. But I would look at the discussion in #3484 where this was changed.

Please find below the code

import { applyMiddleware, createStore, Store } from 'redux'
import { createEpicMiddleware } from 'redux-observable'
import { Persistor, persistReducer, persistStore } from 'redux-persist'
import storage from 'redux-persist/lib/storage'
import { composeWithDevTools } from 'remote-redux-devtools'


export class StoreServices {
  public persistor: Persistor
  public currentStore: Store<ReduxState>

  constructor() {
    const epicMiddleware = createEpicMiddleware(rootEpic, {
      dependencies: epicDependencies
    })

    const persistConfig: any = {
      key: 'root',
      storage,
      whitelist: ['mobileContent']
    }

    const persistedReducer = persistReducer<any, any>(persistConfig, reducer)
    const composeEnhancers = composeWithDevTools({ realtime: EnvironmentSelector.currentEnv, hostname: 'localhost', port: 8080 })
    const store = createStore<any, any, any, any>(
      persistedReducer,
      composeEnhancers(applyMiddleware(epicMiddleware))
    )

    this.currentStore = store
    this.persistor = persistStore(store)
    epicMiddleware.replaceEpic(rootEpic)
  }
}
