Protocol "https:" not supported. Expected "http:"

[WhoisUnknown]

Hello. Thanks for you work.

I migrate from version 0.12.7 to 0.23.0 and get an error when I use http proxy

node:_http_client:189
    throw new ERR_INVALID_PROTOCOL(protocol, expectedProtocol);
    ^

TypeError [ERR_INVALID_PROTOCOL]: Protocol "https:" not supported. Expected "http:"

  code: 'ERR_INVALID_PROTOCOL'
}

Node.js v18.16.1

I am using https-user-agent and http proxy to it.

Version 0.12.7 this worked with proxy correctly

I made demo repository https://github.com/WhoisUnknown/example-interseptor

Hi, @WhoisUnknown.

The proxy URL you are constructing is not a valid URL in Node.js:

// node_modules/https-proxy-agent/dist/index.js@53
 this.proxy = typeof proxy === 'string' ? new URL(proxy) : proxy;

The https-proxy-agent throws an error regarding that:

TypeError [ERR_INVALID_URL]: Invalid URL
    at __node_internal_captureLargerStackTrace (node:internal/errors:490:5)
    at new NodeError (node:internal/errors:399:5)
    at URL.onParseError (node:internal/url:565:9)
    at new URL (node:internal/url:645:5)
    at HttpsProxyAgent (/node_modules/https-proxy-agent/src/index.ts:53:44)

Once I fix the URL, the protocol error surfaces again.

const resultUrlProxy = 'http://example.com'

This should be fixed by #515.

@kettanaito do you have a plan soon to merge and publish #515 ? We have also some issues with proxies and getting exact the same error.
