Error in requests version 2.31.0 with urllib3 2.2.1 and 2.10 raise IncompleteRead(self._fp_bytes_read, self.length_remaining) about requests

[pcor]

I have installed an empty enviroment with conda and requests:

python 3.12.2
requests 2.31.0
urllib3 1.26.18

And we have no errors, when I install urllib3 2.1.0, the program crashes, Below is a simple test program that crashes.

python 3.12.2
requests 2.31.0
urllib3 2.1.0

import requests
from io import BytesIO


class Test():
    def __init__(self):
        self.proxy = None
        self.headers = {}
        self.headers['Connection'] = 'close'
        self.headers['User-Agent'] = 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/123.0.0.0 Safari/537.36'
        self.headers['Accept'] = '*/*'
        self.headers['Accept-Encoding'] = 'gzip, deflate'
        self.session = requests.Session()

    def get(self, url):
        self.session.headers = self.headers
        r = self.session.get(url, proxies=self.proxy, allow_redirects=True, stream=True)
        raw_content = r.raw.read()
        content_length = len(raw_content)
        r.raw._fp = BytesIO(raw_content)
        content=r.text
        with open('test.html', 'w', encoding='utf-8') as fo:
            fo.write(content)

lurl = 'https://www.nolon.es/es/es/comprar?MainUseId=&Invest=False&ClassId=&HighlightTypeId=&PropertyTypeId=&DistrictId=30&CountyId=&AreaRange.MinValue=&AreaRange.MaxValue=&PriceRange.MinValue=0&PriceRange.MaxValue=&CampaignId=&PropertyId=&ResultsPerPage=27&SortOrderBy=DescendingDate&SortOrderBy=DescendingDate'
Test().get(lurl)`

This is the error I get:

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

You must never call r.text or r.content after consuming the underlying response data. That's you're actual bug. I suspect requests and urllib3 were silently returning nothing but you're code has always been the issue
