Plugins no longer working with error: Unsupported callback API version: version 2.0 added a callback_api_version, see migrations.md

Paho-mqtt now has a new version 2.x of their library which is breaking plugins.

You will see this error in the log:

ValueError: Unsupported callback API version: version 2.0 added a callback_api_version, see migrations.md 

Traceback (most recent call last):

ValueError: Unsupported callback API version: version 2.0 added a callback_api_version, see migrations.md 

This impacts new installation of plugins. Plugins already installed will continue to work as long as they are not reinstalled.

On monday a new UDI interface will be release to fix this. Stay tuned.

Thanks for the fix!

The fix to the interface is implemented. 

If you have a plugin with the error, delete and reinstall the plugin.

Please be aware of these changes in the new interface:

I opened a ticket on this error as my YoLink devices aren't working any longer after I did the latest updates.  I've checked all the logs, and the error you posed above is the error I'm seeing in the YoLink node log when I restart the node server.  Can you please tell me how to fix this?

Thanks gzahar, after trying other things, I did delete and recreate the NS plugin and it fixed most of the problem.  I still had to go in and correct some of my IF statements related to the YoLink devices, but the deletion and recreation solved most of the issue.  Thanks again!
