This is a sirv package issue.

const polka = require('polka');

const { PORT = 3000 } = process.env;
const serve = require('sirv')('public');

polka()
  .use(serve)
  .get('/health', (req, res) => {
    res.end('OK');
  })
  .listen(PORT, () => {
    console.log(`> Running on localhost:${PORT}`);
  });
