i haven’t tried to deploy this, but something like this may work in your remix.config.js

- server: process.env.NODE_ENV === "development" ? undefined : "./server.js",
+ server: !process.env.VERCEL ||process.env.NODE_ENV === "development" ? undefined : "./server.js",

if i remember correctly, vercel will set the VERCEL environment variable for you when building. otherwise you could also check for process.env.NODE_ENV === "development" instead

remix build will set NODE_ENV to production so the custom server is included.

Ah, the server.js can only be included in Vercel, so we need to make sure it’s excluded when creating the production build locally.
