'NoneType' object has no attribute '__module__'

We are getting a Sentry issue reported by Sentry. The issue happens in Celery executed code.

MESSAGE

Signal handler <bound method SentryCeleryHandler.process_failure_signal of <raven.contrib.celery.SentryCeleryHandler object at 0x7f7ba702e450>> raised: AttributeError("'NoneType' object has no attribute '__module__'",)

Exception: AttributeError 'NoneType' object has no attribute '__module__'

The offending code looks to be this: def should_capture(self, exc_info): exc_type = exc_info[0] exc_name = '%s.%s' % (exc_type.__module__, exc_type.__name__) exclusions = self.ignore_exceptions

Python: 2.7.11 raven-python: 5.32.0 celery: 4.0.2

I only got this problem when I tried to use client.captureException outside of a try/except block.

[sorrat]

Sort of workaround for using captureException outside try/except block:

import sys

import raven


def get_exc_info():
    exc_info = sys.exc_info()
    if exc_info[0] is None:
        return None
    return exc_info


def capture_exception(error)
    sentry = raven.Client(...)
    exc_info = get_exc_info()
    if exc_info:
        sentry.captureException(exc_info)
    else:
        sentry.captureMessage(error)
