AWS Lambda 挂起，直到它在条带发票列表上超时

Question

我正在使用 AWS Lambda 来托管一个 nodeJs 服务，该服务在 Stripe 上获取我的未结发票并执行付款并更新我的数据库。问题是大部分时间，但不是所有时间（有时一切都按预期进行），它挂在发票列表的调用上，什么都不做。

这是日志停止的代码部分：

const stripe = require('stripe')(process.env.STRIPE_SECRET_KEY, {
    maxNetworkRetries: 1,
    timeout: 2000
});
[other imports]

const microservice = async (event, context, callback) => {
    [some code including database connection]

    console.log('retrieving all open invoices...')
    let invoices;
    try {
        invoices = await stripe.invoices.list({
            status: 'open',
            limit: 100,
        });
        console.log(invoices.data.length + ' data retrieved.');
    } catch (error) {
        console.log('Unable fetch stripe invoices : ', error);
        console.log('Exiting due to stripe connection error.');
        reports.push(new Report('Unable fetch stripe invoices', 'ERROR'));
        return {
        statusCode: 500,
        };
    }
    
    [code that process invoices]

    return {};
};
module.exports.microservice = microservice;

这里是日志输出：

当一切顺利时就是这样:

我不明白为什么它没有错误或日志挂起...

Answer 1

网络问题的发生可能有多种原因。在你的情况下，你可以尝试做的是减少限制（例如 limit : 30）并设置你的客户端库通过设置 maxNetworkRetries : 3 或适合你的应用程序的数字再次重试连接。设置后，Stripe 将在发生超时错误时重试连接。

Answer 2

这是 Step functions use cases 的绝配。它将允许您协调获取发票和处理它们的步骤，并在出现错误时轻松设计重试机制。

Answer 3

这不是真正的解决方案，但导致问题的原因是 Stripe 需要很长时间才能 return 少于 100 个结果。
