So I'm getting Uncaught Error: when using a middleware builder function, an array of middleware must be returned

This is my code

import {
  configureStore,
  compose,
  combineReducers,
  applyMiddleware
} from "@reduxjs/toolkit";
import thunk from "redux-thunk";

const rootReducer = combineReducers({});

const middleware = applyMiddleware(thunk);
const composeWithDevTools = 
  window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;
const composedMiddleWare = composeWithDevTools(middleware)

const store = configureStore({
  reducer: rootReducer,
  middleware: composedMiddleWare,
  devTools: 
    window.__REDUX_DEVTOOLS_EXTENSION__ && window.__REDUX_DEVTOOLS_EXTENSION__()
})

export default store;
