My script consumes gitlab API using certificate. When I run the code below, I got this error, ssl verification error:

requests.exceptions.SSLError: HTTPSConnectionPool(host='gitlab-pprd.oncf.net', port=443): Max retries exceeded with url: /api/v4/projects (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1056)')))
An error occurred: HTTPSConnectionPool(host='gitlab-pprd.oncf.net', port=443): Max retries exceeded with url: /api/v4/projects (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1056)')))

This is my script:

# consumer/management/commands/consume_gitlab_api.py

import logging
import requests
from django.core.management.base import BaseCommand
import certifi


class Command(BaseCommand):

    def handle(self, *args, **kwargs):
        # Configure logging
        logging.basicConfig(level=logging.DEBUG)
        logger = logging.getLogger(__name__)

        logger.info("Starting the consume_gitlab_api management command...")

        gitlab_api_url = 'https://gitlab-pprd.net/api/v4/projects'  
        headers = {
            'PRIVATE-TOKEN': ''
        }

        ca_cert_path = 'C://Users//user//Desktop//consumeapi//gitlab-pprd.net.cert.pem'
        



        try:
            logger.debug("Making request to GitLab API...")
            response = requests.get(gitlab_api_url, headers=headers, verify=ca_cert_path)
            logger.debug(f"Received response: {response.status_code}")

            if response.status_code == 200:
                self.stdout.write(self.style.SUCCESS('Successfully fetched data from GitLab'))
                self.stdout.write(str(response.json()))  # Convert to string to avoid printing errors
                logger.info("Successfully fetched data from GitLab")
            else:
                self.stderr.write(self.style.ERROR('Failed to fetch data from GitLab'))
                self.stderr.write(f'Status code: {response.status_code}')
                self.stderr.write(f'Response: {response.text}')
                logger.error("Failed to fetch data from GitLab. Status code: %s, Response: %s", response.status_code, response.text)
        except Exception as e:
            logger.exception("An error occurred while fetching data from GitLab: %s", e)
            self.stderr.write(self.style.ERROR(f"An error occurred: {e}"))

I tried changing certificates, work with sessions nothing happens.
