Does requests proxy not support https?

it is correct to write the code in this way. The IP of the agent is valid, and HTTP, is supported as well as HTTPS

const request = require("request");

let proxyUrl = "http://119.117.29.15:8943";
request.get({
    url  : "https://pv.sohu.com/cityjson?ie=utf-8",
    proxy: proxyUrl
}, (err, rep, body) => {
    console.log(err);
    console.log(body);
});

but it won"t work if I change the requested proxy to https,. How to solve this problem

let proxyUrl = "https://119.117.29.15:8943";

the error is as follows:
