Even after setting 301 redirect, Google Search Console displays 301 redirect error

Question

I want to change my web address to a different domain, and I have added 301 Redirect to my old site, but it still shows an error.

Here is the screenshot of Vercel:

and the CURL response is 301:

What shall I do to fix this error?

Answer 1

It is actuelly not an error. You are trying to fetch a home page with a 301 redirect on it and Google is telling you that you can not fetch it because it doesn't exist anymore.
You can now simply fetch the 301 targeted url (dlhairyashah.dev).

I checked your redirect and that works fine.
