Regression after v0.7.1

[devfox-se]

Describe the bug
I am using an AWS EC2 instance as a proxy server (custom configured squid3 server) to send a request to (for example) https://jcrew.com
My code works when I use version 0.7.1 but fails after upgrading to 0.7.3, tested on 0.7.2 just in case and it fails too

To Reproduce
Install 0.7.1

from curl_cffi.requests import Session

request_args = {
    "allow_redirects": True,
    "cookies": {},
    "data": b"",
    "headers": {
        "Accept": "text/html,application/xhtml xml,application/xml;q=0.9,*/*;q=0.8",
        "Accept-Encoding": "gzip, deflate",
        "Accept-Language": "en",
    },
    "impersonate": "chrome120",
    "method": "GET",
    "params": None,
    "proxy": "http://255.255.255.255:3128",
    "url": "https://www.jcrew.com/",
}
with Session() as client:
    r = client.request(**request_args)
    assert r.status_code == 200 # OK

Install 0.7.2 or 0.7.3
For some reason it works without specifying a PROXY server

from curl_cffi.requests import Session

request_args = {
    "allow_redirects": True,
    "cookies": {},
    "data": b"",
    "headers": {
        "Accept": "text/html,application/xhtml xml,application/xml;q=0.9,*/*;q=0.8",
        "Accept-Encoding": "gzip, deflate",
        "Accept-Language": "en",
    },
    "impersonate": "chrome120",
    "method": "GET",
    "params": None,
    "url": "https://www.jcrew.com/",
}
with Session() as client:
    r = client.request(**request_args)
    assert r.status_code == 200 # OK

BUT fails once proxy is specified

from curl_cffi.requests import Session

request_args = {
    "allow_redirects": True,
    "cookies": {},
    "data": b"",
    "headers": {
        "Accept": "text/html,application/xhtml xml,application/xml;q=0.9,*/*;q=0.8",
        "Accept-Encoding": "gzip, deflate",
        "Accept-Language": "en",
    },
    "impersonate": "chrome120",
    "method": "GET",
    "params": None,
    "proxy": "http://255.255.255.255:3128",
    "url": "https://www.jcrew.com/",
}
with Session() as client:
    r = client.request(**request_args)  # ERROR raised
    assert r.status_code == 200

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/Users/devfox/projects/test.py", line 19, in <module>

Expected behavior
The code should work just fine on newer versions
