Only me?

 > Build error occurred
Error: supabaseKey is required.
at new SupabaseClient (/vercel/workpath0/node_modules/@supabase/supabase-js/dist/main/SupabaseClient.js:48:19) at createClient (/vercel/workpath0/node_modules/@supabase/supabase-js/dist/main/index.js:25:12)

My initSupabase.tsx

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

const SUPABASE_URL = "https://xxxx.supabase.co";
const SUPABASE_KEY = process.env.NEXT_PUBLIC_SUPABASE_KEY || "";

export const supabase = createClient(SUPABASE_URL, SUPABASE_KEY);

My environment.
--Next.js
--Typescript
--Vercel

Thanks to you, I was able to notice.
The env.production.local file was not uploaded to the production environment.
It's my mistake.
Thank you very much.
