Auth not working after deployment to Vercel

[Shivansh-yadav13]

I have followed the Readme file and deployed my app but there is 1 issue, on my localhost:3000 authentication works perfectly but after deploying it to vercel it does not work and the console shows this

https://mzwpeqplxjiupysnwteo.supabase.co/auth/v1/token?grant_type=pkce 401

after making auth request

Failed to load resource: the server responded with a status of 401 ()

I have a failed request in the logs could that be the reason

There was some issue with my ENV variable 😑
