Не удается получить доступ к `action.type`, но можно получить доступ к `action` на редюсере

Я могу получить доступ только к action, но не к action.type на моем редукторе. Я попытался выполнить console.info(action.type), но это дало неопределенное значение.

export const INPUT_EMAIL = 'INPUT_EMAIL'
export const INPUT_PASSWORD = 'INPUT_PASSWORD'

export function inputEmail(email) {
    return {
        type: INPUT_EMAIL,
        email
    }
}

export function inputPassword(password) {
    return {
        type: INPUT_PASSWORD,
        password,
    }
}

// import { INPUT_EMAIL, INPUT_PASSWORD } from './actions';

const initialState = {
    email: '',
    password: '',
}

function loginReducers(state = initialState, action: Object) {
    console.info('zzZaction', action); <-- just found out it's existing 
    if (typeof state === 'undefined'){
        return initialState
    }
    // switch (action.type) {
    //     case INPUT_EMAIL: 
    //         return Object.assign({},state, {
    //             email: action.email
    //         })
    //     case INPUT_PASSWORD: 
    //     return Object.assign({}, state, {
    //         password: action.password,
    //     })
    //     default:
    //         return state
    // }
    return state
}


export default loginReducers;
