Unable to use proxy with /function api in v2

[Umzario]

Describe the bug
Hello, this issue is similar to the one described here. I can access a site without using proxy, however, when i set the proxy server and also add authentication to the code, it fails. Below is the logs. I see the logs say proxy authentication failed, but the auth is correct

In terms of authenticating proxy, I followed the guide here(I followed method 1). Maybe there's something i'm missing?

Here's a sample of the function code used:

export default async function ({ page }) {await page.authenticate({username: "...", password: "..."});await page.goto("https://www.example.com");const content = await page.content();let data = {};data["content"] = content;return data;}

To Reproduce
Steps to reproduce the behavior:
Try to access a website using a proxy on the /function api (v2)
