Error message using Advanced Search 3.4.14

I just installed and activated Advanced Search version 3.4.14. When I open the Advanced Search page in the end-user interface I see this error message:

Warning : Undefined property: Laminas\View\Helper\Layout::$site in /home/pvikarch/public_html/Staging/modules/AdvancedSearch/view/common/advanced-search/item-sets.phtml on line 27

How can I fix this error?

This is fixed in 3.4.15.

Thanks. Now I do not replicate the error message.
