Troubleshooting PubNub Python SDK

How to enable logging

Use this code to enable logging: 

import pubnub
import logging

pubnub.set_stream_logger('pubnub', logging.DEBUG)

How to find the version of your SDK

You can access your SDK version via constant: 

from pubnub.pubnub import PubNub

PubNub.SDK_VERSION

Error handling with sync()

In case of sync() calls errors will be wrapped out by either Envelope or PubNubAsyncioException which both implement two object fields:

  • e.result - a request result object in case of success, otherwise None

  • e.status - PNStatus object with useful information about the finished request. You may check if it was an error or a success using e.is_error() helper.

sync() usage 

try:
    e = pubnub.publish().channel("my_channel").message("hello!").sync()
    print(str(e.result))
except PubNubException as e:
    print("Error %s" % str(e))
    if status is not None:
        print("Error category #%d" % e.status.category)

Error handling with async()

async() call lets you check for errors using status.is_error() helper:

def callback(result, status):
    if status.is_error():
        print("Error %s" % str(status.error_data.exception))
        print("Error category #%d" % status.category)
    else:
        print(str(result))
