Sveltekit deployment on vercel failed because of Error [LibsqlError]: URL_INVALID: The URL is not in a valid format

Using sveltekit with turso and drizzle-orm, the only similar issue I got is: https://github.com/tursodatabase/libsql/issues/1121the website is working fine on local if I use url: process.env.TURSO_URL!, its build is also working, but on vercel its failing, I've uploaded my .env file on vercel.

db.ts

import 'dotenv/config';import { createClient } from '@libsql/client';import { drizzle } from 'drizzle-orm/libsql';import * as schema from './schema';export const client = createClient({    url: import.meta.env.TURSO_URL!,    authToken: import.meta.env.TURSO_AUTH_TOKEN});export const db = drizzle(client, { schema });

drizzle.config.ts

import { Config } from 'drizzle-kit';import 'dotenv/config';export default {    schema: './src/lib/db/schema.ts',    out: './migrations',    driver: "turso",    dbCredentials: {        url: process.env.TURSO_URL!,        authToken: process.env.TURSO_AUTH_TOKEN    }} satisfies Config;

heres the full error:
