Process finished with exit code 245

Several http requests are made in a loop. In other words, this function was called several times:

import requests
def execute_request(ad_entity, data, url=None):
    data_bytes = json.dumps(data, ensure_ascii=False).encode("utf-8")

    headers = get_headers()

    URL = url or '{}{}/'.format(API_ADDRESS, ad_entity.value.lower())

    response = requests.post(URL, headers=headers, data=data_bytes,
                             verify=False)

The problem seems to have something with thread safety in python itself. It doesn't seem to have something with Django. I tried to solve it by adding sleep up to 2 seconds between requests. It didn't help as far as I can see to the best of my ability.

Could you give me a kick here: 1. What does this code mean and where to read about it? 2. Is there any solution to this problem? 3. Can I switch on a more elaborate logging or find a more in-depth log somewhere? 4. Anyway, how to localize this problem?

Answer 1

These warnings are coming from the urllib3 module due to the HTTPS certificate verification being disabled.

The part responsible for that would be the verify=False to fix it simply remove it or replace it by verify=True (default)

Another way to suppress the warnings ( highly not recommended ) would be to add the following before importing requests:

import urllib3
urllib3.disable_warnings()
