rejectUnauthorized not work for me

[xiaomengheiheihei]

The usage version is as follows：

"name": "urllib",
"version": "3.18.1",

code

import { request, ProxyAgent } from 'urllib';

let res = await request(url, {
    timeout,
    method,
    headers: headers,
    data: query,
    gzip: true,
    rejectUnauthorized: false,
    dispatcher: proxyAgent ? proxyAgent : null
  });

Still reporting errors ：UNABLE_TO_VERIFY_LEAF_SIGNATURE
