App Not working with Vaadin 23.0.9

[snaphalo]

I keep getting a blank page with [object, Object] in it.
The error is: Type error cannot read properties of null (reading 'shadowRoot')

It seems that no example is working with Vaadin 23 and version 5.1.0. I've tried 14 with version 4.0.0 and everything is fine. I've tried Vaadin 22 (4.0.0) and everything worked as expected.

Thanks

Hello. I tested version 5.1.0 in a Vaadin 23.0.9 application and it works okay (see applayouttest.zip). If you're using Spring, please make sure you add com.flowingcode to the vaadin.whitelisted-packages property in your application.properties file.
Also we advice to run mvn vaadin:dance between every vaadin version change so node modules dependencies are update correctly.

Hello!
Thanks for the reply. Yes I've put com.flowingcode into the whitelisted-packages. I've tried with a brand new vaadin 23 install (todo demo). I will give your test a try later and let you know

Thanks for your time

Thank you very much for your help and the great addon. Seems that the problem was with the vaadin:dance. Didn't know about it.

Thanks!!!
