Custom logger is not being triggered when DEBUG=False

I have the following piece of code in settings.py:

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'filters': {
        'require_debug_true': { '()': 'django.utils.log.RequireDebugTrue', },
    },
    'handlers': {
        'console': {
            'filters': ['require_debug_true'],
            'class': 'logging.StreamHandler',
        },
        'kodular': {
            'level': 'WARNING',
            'class': 'account.reporter.KodularExceptionHandler',
        },
    },
    'loggers': {
        'django': {
            'handlers': ['console', 'kodular'],
            'level': os.getenv('DJANGO_LOG_LEVEL', 'DEBUG'),
        },
    },
}

The KodularExceptionHandler class looks like this:

from copy import copy
import json
import logging
import requests

from django.conf import settings
from django.utils.log import AdminEmailHandler
from django.views.debug import ExceptionReporter

class KodularExceptionHandler(AdminEmailHandler):
    def emit(self, record, *args, **kwargs):
        print("Triggered")
        try:
            request = record.request
            subject = record.getMessage()
        except Exception:
            return

        if record.exc_info:
            exc_info = record.exc_info
        else:
            exc_info = (None, record.getMessage(), None)

        reporter = ExceptionReporter(request, is_email=True, *exc_info)
        message = "%s\n\n%s" % (self.format(copy(record)), reporter.get_traceback_text())

        text = "**Error Level**: *%s* | **Status Code**: `%s`\n\n\n" % (record.levelname, record.status_code)

        url = 'https://api.github.com/repos/'+settings.GITHUB_ORG+'/'+settings.GITHUB_REPO+'/issues'
        session = requests.Session()
        session.auth = (settings.GITHUB_USERNAME, settings.GITHUB_PASSWORD)
        issue = {'title': subject,
                'body': text+message.replace('*', '\*').replace('_', '\_'),
                'labels': ["error"]}
        r = session.post(url, json.dumps(issue))
        if r.status_code != 201:
            return
        github_issue_url = json.loads(r.content)['html_url']



        if record.levelname == "WARNING":
            return

        attachments =  [{
            'title': subject,
            'color': 'danger',
            'actions': [{
                'type': 'button',
                'text': 'Github Issue',
                'url': github_issue_url,
                'style': 'primary',
            }],
            'fields': [{
                "title": "Level",
                "value": record.levelname,
                "short": True
            },{
                "title": "Method",
                "value": request.method if request else 'No Request',
                "short": True
            },{
                "title": "Path",
                "value": request.path if request else 'No Request',
                "short": True
            },{
                "title": "User",
                "value": ( (request.user.username + ' (' + str(request.user.pk) + ')'
                        if request.user.is_authenticated else 'Anonymous' )
                        if request else 'No Request' ),
                "short": True
            },{
                "title": "Status Code",
                "value": record.status_code,
                "short": True
            },{
                "title": "UA",
                "value": ( request.META['HTTP_USER_AGENT']
                        if request and request.META else 'No Request' ),
                "short": False
            },{
                "title": 'GET Params',
                "value": json.dumps(request.GET) if request else 'No Request',
                "short": False
            },{
                "title": "POST Data",
                "value": json.dumps(request.POST) if request else 'No Request',
                "short": False
            }]
        }]

        data = { 'payload': json.dumps({'attachments': attachments}) }
        webhook_url = settings.SLACK_HOOK
        r = requests.post(webhook_url, data=data)

When I set DEBUG = True in settings, everything works properly: console handles the error (and prints "Reached"), Github issue gets created and Slack notification is sent.

 

However, if I set DEBUG = False, things go wrong. As it's supposed to be, console outputs less information; but neither Github issue gets created or Slack notification is sent.

I think there is an issue somewhere on the logger handler. It looks like KodularExceptionHandler is not being triggered, as console doesn't print "Reached", whereas when debug is enabled it does.

Any idea what can be causing the custom error reporting class of not being triggered when debug is set to false?

There was a little issue on my urls.py file. I am using custom error pages handlers:

from account import views

handler404 = views.error404
handler500 = views.error500

However, the file views.py looks like this:

from django.shortcuts import render

from account.admin import requires_login

def error404(request, *args, **kwargs):
    return render(request, 'error/404.html')

def error500(request, *args, **kwargs):
    return render(request, 'error/500.html')

I fixed everything by changing it to

from django.shortcuts import render

from account.admin import requires_login

def error404(request, *args, **kwargs):
    return render(request, 'error/404.html', status=404)

def error500(request, *args, **kwargs):
    return render(request, 'error/500.html', status=500)
