Undici throws a V8 error with node 12.19.0

[pantharshit00]

Undici 2.0.5 is throwing a V8 stack trace when used with node version 12.19.0

node[28363]: ../src/node_http_parser_impl.h:529:static void node::(anonymous namespace)::Parser::Initialize(const FunctionCallbackInfo<v8::Value> &): Assertion `args[3]->IsInt32()' failed.

The above error doesn't happen with node 12.18.4 or 14.13.0. Node 12.19 was released on Oct 6. I think this is related to use of native http_parser from node via process.binding:

undici/lib/node/http-parser.js

Line 4 in 1c628a9

const { HTTPParser } = process.binding('http_parser') // eslint-disable-line

Reproduction

// server.js
"use strict";

const { createServer } = require("http");

createServer((req, res) => {
  res.end("hello world");
}).listen("/var/tmp/undici.sock");

// client.js
const { Client } = require("undici");
const { Writable } = require("stream");

const client = new Client(`http://localhost`, {
  socketPath: "/var/tmp/undici.sock",
});

client
  .request({
    path: "/",
    method: "GET",
  })
  .then(({ body }) => {
    body.pipe(
      new Writable({
        write(_, __, callback) {
          callback();
        },
      })
    );
  });

Run server.js and then run client.js to reproduce.

💚 Many thanks! That was super fast @ronag ⏩

[Jolg42]

@ronag Do you plan to release a new version to npm in the next days maybe?

Hmm, @ronag I am still able to reproduce the error in 2.0.6:
