2.1.0 - Protocol https not supported. Expected http

[mfinegold-cambia]

Hello, we're on an old version of node ( v8.16.1 ) and superagent ( 4.1.0 ), and noticed when we upgraded to your new superagent-proxy version 2.1.0 recently that it broke our code that uses it to make a https call though our company egress proxy. The same code was working fine with superagent-proxy 2.0.0.

The error making the https call was "Error: Protocol https not supported. Expected http:"

For now we'll revert to using 2.0.0, but wondering if any idea?

I'm having the same issue under very specific circumstances.

The issue started to appear once we installed Sentry (I know this looks bad, but even without Sentry there should have been logs if the error occurred before).

Downgrading superagent-proxy to 2.0.0 or disabling Sentry or upgrading Sentry to 6.14.1 seems to work.

Also I found this getsentry/sentry-javascript#4080

Config:

• node 12.16.3
• superagent 6.1.0
• superagent-proxy 2.1.0
• @sentry/node 6.14.0

Code to reproduce:

const request = require('superagent');
const proxy = require('superagent-proxy');
const Sentry = require('@sentry/node');


Sentry.init({
  dsn: '<Your sentry DSN>',
});

proxy(request);

async function main() {
  try {
    const {text} = await request
      .get('https://example.com')
      .proxy('<Your proxy URL>');

    console.log(text);
  } catch (err) {
    console.error(err);
  }
}

main();

Hope this helps
