I'm sorry to hear that you're experiencing issues with your Vercel serverless function. Based on the information provided in the extracts, there could be several reasons why this is happening. Here are a few potential issues and solutions:
-
Dynamic Pages Issue: There was a reported issue where dynamic pages were causing the Vercel serverless function to crash when deploying. This issue was specifically related to an Astro SSR project using a Vercel adapter. If this is similar to your case, you might want to check the status of this issue or look for similar ones in the Astro GitHub repository here (https://github.com/withastro/astro/issues/9153).
-
Serverless Code Splitting: Astro has a feature that allows serverless code splitting on each route, which can improve response time by removing unused code. If you're experiencing slow response times or crashes, you might want to enable this feature by specifying
{ functionPerRoute: true }in your Astro configuration file. More details can be found here (https://astro.build/blog/vercel-official-hosting-partner#serverless-code-splitting). -
Dependency Issues: There have been reported issues with certain dependencies causing the Vercel serverless function to crash. For example, one issue was related to the "image-size" module. If your project uses this or similar dependencies, you might want to check if they're causing the problem. More details can be found here (https://github.com/withastro/astro/issues/6521).
-
Prerendered Routes: There's an open issue where the Vercel adapter generates serverless functions for all routes, including prerendered ones, when the
functionPerRouteparameter is set totrue. This could potentially cause issues. More details can be found here (https://github.com/withastro/astro/issues/10211).
Remember to always check your logs for any error messages, as they can provide more specific information about what's causing the crash. If none of the above solutions work, you might want to consider reaching out to the Astro community or Vercel support for further assistance.
Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

Let me check the knowledge base for you. One moment! :books:
To make your index page server-side rendered (SSR) in Astro, you need to follow these steps:
- Configure Astro for SSR: Update your
outputconfiguration to one of the two server-rendered modes. For example, if you want every page to be rendered on demand by default, addoutput: 'server'to your Astro config. Here's an example of how to do this:
// astro.config.mjs
import { defineConfig } from 'astro/config';
import node from "@astrojs/node";
export default defineConfig({
output: 'server',
adapter: node({ mode: "standalone" })
});
Source (https://docs.astro.build/en/guides/server-side-rendering#configure-server-or-hybrid)
- Opt-in to Pre-rendering: Add
export const prerender = trueto your index page to pre-render it as a static page. Here's an example of how to do this:
// src/pages/index.astro
---
export const prerender = true;
// ...
---
<html> <!-- Static, pre-rendered page here... --></html>
