How to connect the APNS certificate correctly?

Question

Django

There is a function to send messages

PUSH_NOTIFICATIONS_SETTINGS = {
        "APNS_CERTIFICATE": os.path.join(PROJECT_ROOT, 'rss/CorruptionDevPushCer.p12'),
}

from rss.settings import PUSH_NOTIFICATIONS_SETTINGS

def send_message(data, kwargs):
    device_apns_ids = [d.device_id for d in UserDevice.objects.filter(client=client, active=True, device=2).all()]
    cert_file = PUSH_NOTIFICATIONS_SETTINGS['APNS_CERTIFICATE']
    apns_enhanced = APNs(use_sandbox=True, cert_file=cert_file, enhanced=True)
    payload = Payload(alert=kwargs['pid'], sound="default", badge=1)
    frame = Frame()
    identifier = 1
    expiry = time.time() + 3600
    priority = 10
    for device_apns_id in device_apns_ids:
        device_apns_id = str(device_apns_id)
        frame.add_item(device_apns_id, payload, identifier, expiry, priority)

    apns_responce = apns_enhanced.gateway_server.send_notification_multiple(frame)

The result of the work

[Errno 336265218] _ssl.c:355: error:140B0002:SSL routines:SSL_CTX_use_PrivateKey_file:system lib

Where is the mistake?

Thank you all
Here is an example that normally shows how to do it

An error arose, because I did not write the relative paths to the certificate correctly
