IllegalArgumentException: Container 'speakersDc' not found

I am following the tutorial CUBA Studio Quick Start – CUBA Platform until Running the application in development mode. When i run the application and create a new session. The error below appear

Hi,

It looks like the container’s name is wrong, it might be a typo in the screen’s layout XML. You can attach app sources to the message on the forum so we could have a look.

Thank you i figure that out. I missed including the lookup component

Glad to hear that!
