Supabase - Google SSO setup on Render

I have a monorepo with a FastAPI backend and Next.js frontend. Both are running on Render host. We are setting up Supabase / Google SSO. Currently the app runs perfectly on localhost - users can sign in / out and we can display a table of all users. On the Render host, users can sign in - out, BUT we CANNOT display a table of all users. The environment variables on local .env and the Render host environment are identical. We have been working on this bug for a week with no solution. Any ideas or direction would be immensely helpful.
