当尝试在窗口上执行分派操作时，我遇到此错误：“未捕获的TypeError：分派不是函数”。

我仔细检查了语法。

export const fetchAllSpots = () => dispatch => (
    APIUtil.fetchAllSpots().then(spots => 
    dispatch(receiveAllSpots(spots)))
);

const receiveAllSpots = payload => ({
    type: RECEIVE_ALL_SPOTS,
    payload
});

window.fetchAllSpots = fetchAllSpots();
