Redux middleware with configureStore: Next is not a function - redux

Question

I'm trying to add a custom middleware to my Redux (I'm using it with configureStore)
const reducer = {
layout: layout,
login: login,
companies: companies,
services: services,
platforms: platforms,
report: report,
users: users,
stats: stats,
version: version,
}
const logger = store => next => action => {
console.log('dispatching', action)
let result = next(action)
console.log('next state', store.getState())
return result
}
const store = configureStore({
reducer,
middleware: (getDefaultMiddleware) => getDefaultMiddleware().concat(logger())
});
But I get Uncaught TypeError: next is not a function
Cannot find a working example with configureStore.
The packages that I'm using are:
"react-redux": "^8.0.2",
"redux": "^4.2.0",
"redux-thunk": "^2.4.1",
Update #1
I followed hint of
as following
const reducer = {
layout: layout,
login: login,
companies: companies,
services: services,
platforms: platforms,
report: report,
users: users,
stats: stats,
version: version,
wizard: wizard,
}
const logger = store => next => action => {
console.log('dispatching', action)
let result = next(action)
console.log('next state', store.getState())
return result
}
const middlewareLogger = logger(store)(next)(action);
const store = configureStore({
reducer,
middleware: (getDefaultMiddleware) => getDefaultMiddleware().concat(middlewareLogger())
});
export default store;
but i get
src/reducers/index.js
Line 33:40: 'next' is not defined no-undef
Line 33:46: 'action' is not defined no-undef

One minute after, I found solution, thanks to this post: Why does it says that 'next' is not defined in redux middleware code. Is next method of middleware deprecated?
Error was I'm calling logger() instead of logger.
So, I did't pass any arguments to logger.
Final working code:
const store = configureStore({
reducer,
middleware: (getDefaultMiddleware) => getDefaultMiddleware().concat(logger)
});
