Uncaught TypeError: Providing your root Epic to createEpicMiddleware(rootEpic)

I am getting this error

Uncaught TypeError: Providing your root Epic to createEpicMiddleware(rootEpic) is no longer supported, instead use epicMiddleware.run(rootEpic)

When simply using

import 'rxjs'
import { createStore, combineReducers, applyMiddleware } from 'redux'
import { reducer as formReducer } from 'redux-form'
import thunk from 'redux-thunk'
import promise from 'redux-promise-middleware'
import { createEpicMiddleware, combineEpics } from 'redux-observable'

import app from './app'

// Bundling Epics
const rootEpic = combineEpics(
)

// Creating Bundled Epic
const epicMiddleware = createEpicMiddleware(rootEpic)

// Define Middleware
const middleware = [
  thunk,
  promise(),
  epicMiddleware
]

// Define Reducers
const reducers = combineReducers({
  form: formReducer
})

// Create Store
export default createStore(reducers,window.__REDUX_DEVTOOLS_EXTENSION__ && window.__REDUX_DEVTOOLS_EXTENSION__(), applyMiddleware(...middleware))

Kindly help to resolve this
