Not caught Error: Client network socket disconnected before secure TLS connection was established

[AidanWelch]

It's normal that some proxied requests fail, so I have simple error handling, the issue is that the error is not being caught and instead crashing the script,

import { HttpsProxyAgent } from 'https-proxy-agent';
import fetch from 'node-fetch';

const agent = new HttpsProxyAgent( process.env.PROXY_STRING );

let err;
const casePageResponse = await fetch( `foo.bar`, { agent })
	.catch( e => err = e );

Crashes with this error:

node:events:497
      throw er; // Unhandled 'error' event
      ^

Error: Client network socket disconnected before secure TLS connection was established

}

It doesn't get caught in the catch statement.

Probably an error with node-fetch as seen on this tangentially related issue: node-fetch/node-fetch#892

Actually I get it with node:https too, also not being caught by req.on('error', console.error)

[AidanWelch]

passing rejectUnauthorized like so:

const agent = new HttpsProxyAgent( process.env.PROXY_STRING, { rejectUnauthorized: false });

stops this error specifically, but the issue is still that it doesn't throw the error.
