Hey! The issue is that your sitemap.ts is trying to fetch dynamic data at build time, which might be failing on Vercel. Here’s how to fix it: Option 1: Force Dynamic Rendering Add this to the top of your sitemap.ts file to make it render at request time: export const dynamic = 'force-dynamic' Op…

@anshumanb any idea. can it be an issue on vercel itself because you can’t even see log of the sitemap being acess. The build logs shows sitemap but acessing gives 404. All env variables and endpoints seems to work correctly.

It’s worth trying this: [image] Unable to access sitemap.xml and robots.txt Help Thanks for sharing those details. Are you able to share the public repo or a minimal reproducible example ? Even just sharing some info about how routing is handled in your Rea…

@pawlean @anshumanb any suggestions ?

Hey, @oumeir-rengony ! I dug into the repo and the deployed site a bit more, and this no longer looks like a dynamic-data-fetch problem. What I found: app/sitemap.ts exists and Vercel is recognizing it during build as ƒ /sitemap.xml robots.txt is working fine in production but https://www.ulama-m…

What that would look like: Create app/sitemap.xml/route.ts, like: import { getBayaanSlug } from '@/services/bayaans/bayaan.service'; export const dynamic = 'force-dynamic'; function escapeXml(value: string) { return value .replace(/&/g, '&') .replace(/"/g, '"') .replace(/'…

The same issue. i do think this is a regression with nextjs itself. for now im manually adding a script to add the sitemap after the build.
