Hey @umairfaiser thanks for posting!

When i ran into this, it was actually because i was missing proper environment variables or a config setup for the sitemap. I still had a url pointing to localhost and caused this issue. Can you give your envrionment setup on Vercel a check?

i checked the variables they are all set i mean i dont even have variables in my app.for the urls i have both the urls the localhost and the deploying url.i still cant figure out wats going wrong..
