SSLError: bad handshake, certificate verify failed

Hello,

I'm migrating from criteo-marketing-transition to criteo-api-marketingsolutions-sdk. While the credentials that I'm using work with the former library, I receive the following traceback error on the new one:

This is the code that I'm trying out:

    def test_criteo(self, username: str, password: str):
        from criteo_api_marketingsolutions_v2022_10 import Configuration, ApiClient
        from criteo_api_marketingsolutions_v2022_10.api.audience_api import AudienceApi

        configuration = Configuration(username=username, password=password)
        client = ApiClient(configuration)
        api = AudienceApi(client)

        print(api.get_audiences())

Any help would be very appreciated, thank you!

I think I found the problem. I upgraded urllib3 to the latest version and now it works.
