In earlier versions history was a peerDependency, this is no longer the case since version 2 has its own history management tool. This means that the arguments passed to connectRoutes(documentation) need to be changed from this:

  const { reducer, middleware, enhancer, thunk } = connectRoutes(
    history,
    routesMap,
    options
  )

to this:

  const { reducer, middleware, enhancer, thunk } = connectRoutes(
    routesMap, {
    ...options,
    initialEntries
  })

If you're using a custom history type, you can still import createHashHistory or createMemoryHistory from either the history package or rudy-history and add to your options as createHistory.

And inside of your configureStore.js file if you are server side rendering, change this:

 const history = createHistory({ initialEntries: [req.path] })
 const { store, thunk } = configureStore(history, preLoadedState)

To this:

 const { store, thunk } = configureStore(preLoadedState, [req.path])
