I have a middleware that runs this chunk of code:
return new Response(dids[subdomain] + "\n", {
status: 200,
statusText: "ok",
headers: {
"content-type": "text/plain"
}
});
It should return status 200 as well as the text/plain response.
When in development on localhost, this acts the way I would expect it to. When in production on Vercel, this returns a 400 as well as the text/plain response.

Hi @idle marten. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
It seems you're experiencing an issue with Astro middleware behaving differently between your local development environment and Vercel deployment. This is likely related to how Vercel handles Astro middleware.
When using Astro middleware with Vercel, there are some specific considerations to be aware of. The Vercel adapter for Astro can run middleware in different ways, which might explain the behavior you're seeing.
By default, Astro middleware runs on Vercel's serverless functions. However, there's an option to run it on Vercel Edge Functions instead, which might handle responses differently. When using edgeMiddleware: true in your Vercel adapter configuration, your middleware code executes as an edge function for all requests, including static assets and rendered pages.
import { defineConfig } from 'astro/config';
import vercel from '@astrojs/vercel';
export default defineConfig({
// ...
adapter: vercel({
edgeMiddleware: true,
}),
});
This configuration might help resolve your issue by ensuring your middleware runs consistently on Vercel's edge network Running Astro middleware on Vercel Edge Functions.
Another thing to check is that your middleware is properly returning a Response object. Astro requires middleware to return a valid Response object or call the next() function. If it doesn't, you might see errors like:
Your code snippet looks correct in terms of returning a proper Response object, but there might be other factors at play in the full middleware implementation.
If you continue to experience issues, you might want to try the example from the Astro documentation for middleware that modifies responses:
export const onRequest = async (context, next) => {
const response = await next();
// Modify the response here
return new Response(modifiedContent, {
status: 200,
headers: response.headers
});
};
