Variable Input - invalid visualization - after importing an app from the old to the new version of Qlik Sense

[Metamagixx]

Hi all,

Lately, updated the Qlik instance from the version May 2022 to February 2024.

I have exported the existing apps from the old instance and then imported to the new one.

Now "Variable input" bundle shows the following error message: invalid visualization

What can be missing here?

What can be done here to solve this issue?
