Fullcalendar module

Hello!
I would like to ask you if anyone has used before cbmodule-fullcalendar on Contentbox running Coldbox 7 without a problem.
Unfortunately i have met several issues from getModel is deprecated to key does not exist in admin layout especially when i try to create a new calendar.

Regards

I also share my box.json. Sorry for saying Coldbox 7 beforehand!
