I'm trying to connect my .env.local file env variables to my application, but it's showing this error.
This is my supabase.ts:

import { createClient } from "@supabase/supabase-js";

const supabaseURL = process.env.NEXT_PUBLIC_SUPABASE_URL!;
const supabaseKEY = process.env.NEXT_PUBLIC_SUPABASE_KEY!;

if (!supabaseKEY || !supabaseURL) {
  throw new Error("Supabase URL and key must be provided");
}

const supabase = createClient(supabaseURL, supabaseKEY);

export default supabase;

I've stored my variables in .env.local, without quotes (as shown)
