Raven python - 'SentryHandler' has no attribute 'level'

I’m trying to add sentry logging to my application.

My imports is:

import sys
import traceback
import hashlib
import yaml
import logging
from subprocess import check_call, call

from raven import Client
from raven.handlers.logging import SentryHandler
from raven.conf import setup_logging

My code is:

sentryEnable = bool(config["sentryEnable"])
if sentryEnable:
    sentryDSN = config["sentryDSN"]
    print("Sentry reporting enabled, sentry DSN was found in config")
    sentryClient = Client(sentryDSN)
    sentryHandler = SentryHandler(sentryClient)
    logger = logging.getLogger(__name__)


AttributeError: type object 'SentryHandler' has no attribute 'level'

So, where am I wrong, and what should I do with it. How can i fix it?
