React-native redux-saga error: takeLatest$1 requires a saga parameter

Question

我创建了一个包含一些组件的应用程序，并在以下组件中使用了 redux-saga：

// AlphaScreen.js
import ... // react & react-native
import { useSelector, useDispatch } from 'react-redux';
import { getUser } from '../redux/ducks/user';

const AlphScreen = props => {
  const dispatch = useDispatch();
  useEffect(() => {
        dispatch(getUser());
    }, [dispatch]);
  const users = useSelector((state) => state.user.user);
  console.log(users);
  return (
    <View><Text>Blah</Text></View>
  );
}

// redux/ducks/user.js
export const SET_USER = "SET_USER";
export const GET_USER = "GET_USER";

export const setUser = (user) => ({
    type: SET_USER,
    user // user: user
});

export const getUser = () => ({
    tye: GET_USER
});

const initialState = {
    user: undefined
};

const userReducer = (state = initialState, action) => {
    switch(action.type) {
        case SET_USER:
            const {user} = action;
            return {...state, user:user};
        default:
            return state;
    }
};

export default userReducer;

// redux/defaultStore.js
import {applyMiddleware, combineReducers, createStore} from 'redux'
import createSagaMiddleware from "redux-saga";
import counterReducer from './ducks/counter'
import userReducer from './ducks/user';
import { watcherSaga } from './sagas/saga';

const reducer = combineReducers({
    user: userReducer
});

const sagaMiddleware = createSagaMiddleware();
const middlewares = [sagaMiddleware];
const store = createStore(reducer, applyMiddleware(...middlewares));

sagaMiddleware.run(watcherSaga)
export default store;

// redux/sagas/saga.js
import { takeLatest } from 'redux-saga/effects';
import { handleGetUsers } from './handlers/user';
import { GET_USER } from '../ducks/user';

export function* watcherSaga() {
    yield takeLatest(GET_USER, handleGetUsers); //<- getting error takeLatest requires a saga parameter
}

// redux/sagas/handlers/user.js
import { call, put } from "redux-saga/effects";
import { setUser } from "../../ducks/user";
import { requestGetUser } from "../requests/user";

export function* handleGetUser(action) {
    try {
        const response = yield call(requestGetUser);
        const { data } = response;
        yield put(setUser(data));
    } catch (error) {
        console.log(error);
    }
}

// redux/sagas/request/user.js
import axios from 'axios'

const requestGetUser = () => {
    return axios.request({
        method: "get",
        url:"https://jsonplaceholder.typicode.com/users"
    });
}

export { requestGetUser };

但是我有以下错误：

The above error occurred in task watcherSaga

有什么修复错误的建议吗？谢谢

对我来说这看起来像是一个错字，handleGetUsers vs handleGetUser :)
