Javascript 如何从 Promise 更新状态变量

我正在try 确定客户是否有活动订阅.为此，我使用以下代码:

const stripe = require('stripe')('some-api-key');

export default function Example(){
    // the user will automatically be considered non-subbed by default
    const [isSubscriber, setIsSubscriber] = useState(false)


    // grab the customer id from stripe
    async function get_customer_id() {

        const customers = await stripe.customers.search({
            query: `metadata[\'some-meta-data-key\']:\'some-meta-data-value\'`
        });
        return customers.data[0]['id']
    }


    // grab the list of active subscriptions from stripe
    async function customer_is_subscriber(){
        const subs = await stripe.subscriptions.list({
            status: 'active',
        });
        return subs
    }


    // determine if the customer id is in the list of active subscriptions. 
    // return true if so, false otherwise
    async function test_equality(){
        const customer_id = await get_customer_id();
        const subbed = await customer_is_subscriber();

        const answer = subbed.find(sub => sub.customer === customer_id)
        return !!answer;
        
    }


    useEffect( () => {
        async function load_result() {
            const promise_function_return = await test_equality()
            setIsSubscriber(promise_function_return)
        }
        load_result();
}, [isSubscriber]);


return (

// some react code

)

}

我已经能够成功地获得我的所有其他功能，其中我正在对用户是否是订阅者进行比较，但我遇到的问题是更新状态值(例如，如果是子床，则为true，否则为false).

我发现了一些关于这个特定主题的好问题，比如:

这里:setState inside Promise in React

这里是:setState inside a Promise function in a useEffect with hooks?

但我就是没能让它正常工作.这是我目前最接近解决这个问题的一次.
