500 SupabaseUrl is required error when deployed on Netlify

Question

I developed an application using NuxtJs3 + supabase. I am using the @nuxtjs/supabase module as well. On my local dev things are working fine but when I deployed this on Netlify, I had the below error-

I rechecked the environment variables settings at Netlify, and SUPABASE_URL and SUPABASE_KEY both are present.

On local my .env file does look like this as mentioned in the document-

SUPABASE_URL=
SUPABASE_KEY=

I have browsed a few issues on GitHub as well, mostly revolving around the .env debugging ways which I already verified. Here are a few-

1. Error: supabaseUrl is required (supabase) postgresql
2. https://www.reddit.com/r/Supabase/comments/13ayvr2/error_supabaseurl_is_required/
3. https://github.com/orgs/supabase/discussions/3218
4. https://community.fly.io/t/supabaseurl-is-required/18010

Can anyone please help in debugging this issue?
