uncaught TypeError exception when using sendStatus with a BigNum

[joshua-rogers-exodus]

I know this is a stupid scenario, but I thought I'd report this bug because it probably is expected that it'll be caught:

// server.js
const express = require('express');
const app = express();

// Catch everything and return 200n
app.use((_req, res) => res.sendStatus(200n));

const port = process.env.PORT || 3000;
app.listen(port, () => console.log(`OK server on :${port}`));

$ node index.js & curl localhost:3000 &>/dev/null

With res.status() or res.sendStatus() → you must pass a regular Number.

BigInt is not valid here, and it wouldn’t make sense to support it since HTTP doesn’t allow it.

what is the reason behind passing a bigint into http server

[dongjour99]

sendStatus() function is for HTTP response with a specific status code. You cannot use Bigint.
