Webix JS

Hello All

I’m about to create a proove of concept for a new web application including backend framework.
I downloaded the GPL version and integrated it into the POC.
When I load the app (in the following the static variant) I always get the following Javascript exception:

webix.js?v=6.3.1:21956 Uncaught TypeError: Cannot read property ‘length’ of undefined
at result._beforeResetBorders (webix.js?v=6.3.1:21956)
at result._parse_cells (webix.js?v=6.3.1:21868)
at new result (webix.js?v=6.3.1:2167)
at _view (webix.js?v=6.3.1:2048)
at _ui_creator (webix.js?v=6.3.1:1939)
at Object.ui (webix.js?v=6.3.1:1907)
at test.html:14

The page I’m trying to load:

Whats wrong here?
