Vercel 通过来自 SvelteKit 应用程序的简单 GraphQL 请求“此无服务器功能已崩溃”

Question

我在初始页面加载时经常遇到看似随机的错误。我认为问题与 Vercel Serverless Functions 有关。

我经常在网站本身上收到此错误：\n

现在，其他人似乎也有类似的问题：

• Vercel + NextJS：在建立安全 TLS 连接之前客户端网络套接字已断开 - 帮助 - Fauna Forums
\n
• node.js - Vercel上部署的Nextjs中的api请求出现504/502错误 - Thinbug

尤其是最后一个链接，看起来问题的根源在于 AWS Lambda。我并不期望有灵丹妙药，但我确实想确保问题确实如我所想（而不是我的代码中的错误）。

有没有人找到任何解决方法？如何最大限度地减少这些功能崩溃的可能性？
