Why isn't the API_PORT variable being loaded? Is there something I'm missing?

import { Hono } from '@hono/hono';
import { load } from "@std/dotenv"
const envVar = await load();

const app = new Hono();
console.log('PORT? ', Deno.env.get('API_PORT'), envVar);
app.get('/', (c) => c.text('Hello Deno!'));
const port = parseInt(Deno.env.get('API_PORT') || '8080');

Deno.serve({ port:  port}, app.fetch);
