I am getting this same issue, Following the guide Next.js Platforms Starter Kit guide resulted in 404 for me.
Cannot even see any error, Can someone please help?

i now have mine working the way i want, although i don't think its what the repo is intended to do.
@Rudrakaniya
could you provide some more specifics about where you are in setting it up? what is the state of your repo? what step are you on in the guide?

I have deployed this repo using Vercel's deployment template. I set up all the required environment variables, but I am unable to open any page; all the pages are giving a 404 error. I tried running it locally as well, and I am able to open the login page at 'http://app.localhost:3000/login,' but it doesn't authenticate the user or allow access to the app.
I am not sure what is wrong, trying to debug..

I tried deploying this repo with vercel's deploy this template functionality and it broke and did not work properly. I then started from scratch with the guide and was able to get it working.

1. have you done this part?:

2. what is the state of your .env file locally?

• have you changed the file name extension to .env?
• what is the value in your NEXT_PUBLIC_ROOT_DOMAIN:?
