The error message states: 'VercelPostgresError - missing_connection_string: You did not supply a connectionString and no POSTGRES_URL env var was found.' I've already added the connection string to my .env file, but the error persists. What could be causing this, and how can I ensure the environment variable is correctly recognized both locally and on Vercel?"
I added a console log in my database connection code to verify the POSTGRES_URL is being read but it's not working
