JavaScript V4 SDK Troubleshooting Guide

How to enable logging

Set logVerbosity to true on initialization.

Note

Always set the UUID to uniquely identify the user or device that connects to PubNub. This UUID should be persisted, and should remain unchanged for the lifetime of the user or the device. Not setting the UUID can significantly impact your billing if your account uses the Monthly Active Users (MAUs) based pricing model, and can also lead to unexpected behavior if you have Presence enabled.

var pubnub = new PubNub({
    subscribeKey: "mySubscribeKey",
    publishKey: "myPublishKey",
    logVerbosity: true,
    uuid: "myUniqueUUID"
});

Note

Copy the logs from the console output of the browser as text and submit to support@pubnub.com
