DEPRECATED: logger, use mx.logger instead -- will be removed in version: 11.0

This warning has been “popping” in the console multiple times per second from the client node since I upgraded to Mendix 9. How may I troubleshoot to check which widget is causing it?

Robert answered a similar question perfectly:

This means you have a widget using “logger” instead of “mx.logger”. If you wrote the widget yourself, just change the code to use mx.logger and deploy a new version. However, if this is from a third party widget, you will need to see if there is a new version in the Marketplace to download and update.

Hope this helps you
