Thank you for providing me the information.
The bug report tells me that the services are not started.
LogGenvid:Error: Genvid_SubmitNotification(Popularity) failed: Disconnected (10).
I’m not sure if you are trying to run the sample from the editor or by running it from the web interface.
From the editor, you can see if the services are running by using the Genvid Plugin Editor.
In the Jobs tab, services and web should be green to run the sample.
In the web interface (Cluster-UI) it should be the same things.
You can find useful information in the documentation section: Local Environment Usage
I hope this will help you.
