Hi @soniv, base on version number (1.1.1.SNAPSHOT) it looks that you are using latest version of WKND - from main branch. According to the documentation https://github.com/adobe/aem-guides-wknd#system-requirements you will need AEM 6.5 with SP10 or newer.
I was able to reproduce this issue on my local machine, and fix it installing SP10. Below you can find direct link to SP10 on Adobe Software Distribution. On that page you will also find all other Service Packs.
Please install Service Pack 10 or later to solve the problem.
