only one launchdarkly client can exist at a time but another client already exists? and other devtools warnings

enter image description here

When running our react web application both locally and in production, I am receiving the following errors and warnings in the Console. This error appears in the Console tab of Chrome Dev Tools when I am running our react web application both locally and in production.

The only warning or error that makes a modicum of sense is the youtube.com error as we have a link to a YouTube video on our home page, and perhaps we are not properly displaying the video.

I am at a complete loss for the rest of these warnings/errors and how to resolve them. We do not use LaunchDarklyClient in our web application at all. These DevTools failed to load source map:... warnings don't provide any context, and the links lead to no where.

Notably, when I run our website in incognito mode, the LaunchDarklyClient error goes away, as do the DevTools failed to load... warnings. Does that mean these warnings/errors are potentially due to some chrome extensions I am using, or something else related to my local chrome?

Solution

  • I did some testing by toggling extensions on and off:

    • adblock plus 3.16 is responsible for DevTools failed to load source map:... warnings
    • compose AI 1.0.0-rc1 is responsible for LaunchDarklyClient errors
    • unrecognized feature: web-share is not related to any of my extensions (still getting this warning when toggling all extensions off)

    Still not sure if there's a way to hide or remove these warnings/errors other than to disable these chrome extensions.
