I created a Nextjs 15 project and deployed with Vercel. I added my custom domain. When I try to add my page to google search console it shows a redirected page error. "The page was not added to the directory: Redirect error".
Says directing page is "http://mydomain.com/user.php?login=" but my app does not have a page like this. When I visit the link, it brings a 403 page of Vercel with an ID.
Why does my project have this kind of a page? My other NextJS projects have this user.php issue too.
If you have a Nextjs hosted app try routing to user.php. Probably you will see it too.
