[SOLVED] Error 400Invalid `success` param: URL host must be one of: localhost, cloud.appwrite.io
Hey when i try to login via google on my next app. I get such error. The redirect link is an app hosted in vercel and has .vercel.app in its domain. How do i fix this issue?
TL;DR
To fix the "Error 400 Invalid `success` param: URL host must be one of: localhost, cloud.appwrite.io" issue when logging in via Google on a Next.js app hosted on Vercel with a .vercel.app domain:
1. Go to your console and navigate to "Settings -> Custom Domains".
2. Add your .vercel.app domain to the list of custom domains.
3. Save the changes.
The issue should be resolved after adding the custom domain. 
In your console you should go to Settings -> Custom Domains and add your .vercel.app domain
would you please add a hostname that has an exact matching hostname (not wildcard)?
