getState() is undefined

Got this error when adding this to my dev middleware.

const middleware = [
  require('redux-immutable-state-invariant').default,
  thunk,
  promise,
]
const store = createStore(
  rootReducer,
  initialState,
  compose(
    applyMiddleware(...middleware),
    DevTools.instrument() // Enable Redux DevTools
  )
)

"redux": "version": "3.6.0"

Remember that what you import from this library is a "middleware factory", which means it's a function you have to call to get the middleware to inject in Redux. So your example should be changed to be like this:

const middleware = [
  require('redux-immutable-state-invariant').default(), // <-- Notice the parens here
  thunk,
  promise,
]
const store = createStore(
  rootReducer,
  initialState,
  compose(
    applyMiddleware(...middleware),
    DevTools.instrument() // Enable Redux DevTools
  )
)

Hope this helps with the issue!
