React-Redux: getState() not available

I've encountered this really frustrating issue with redux and getState(). I have this async thunk:

export const getUser = () => async (dispatch, getState) => {
  try {
    dispatch(requestCurrentUser());
    const user = await apiService.getUser();
    console.log(user);
    debugger;
  } catch (e) {
    dispatch(failureCurrentUser(e));
  }
};

The debugger activates, as it should, but getState() is not defined, only dispatch(). What is weird is that if I step through the call stack and land on the first line export const getUser = () => async (dispatch, getState) => {, getState is defined there but for some reason, when the function starts executing, it becomes unavailable.

If it is of any importance - I'm calling getUser() in the root file of the project, in a useEffect() like this:

  useEffect(() => {
    store.dispatch(getCurrentUser());
  }, []);

I have to call it via store since this root component renders the <Provider />.

Also, I'm using redux-toolkit and now migrating gradually from pure redux, hence the action.

Devtools will remove unused variables from scope, when you run the below code in console and at the debugger breakpoint try to access value you'll get Uncaught ReferenceError: value is not defined error.

function test (value){
  console.log('value is fine here:',value);
  return function something(){
   //here try to console log value in the console
   debugger;
   return 88
  }
}
test(22)()

So in your code you can just use getState and it will not be removed after optimization:

export const getUser = () => async (dispatch, getState) => {
  try {
    //using getState here so it won't be removed from scope
    console.log(getState);
    dispatch(requestCurrentUser());
    const user = await apiService.getUser();
    console.log(user);
    debugger;
  } catch (e) {
    dispatch(failureCurrentUser(e));
  }
};
