Grid don't render


I have a problem with a group of grids, (The grids do not look).
where the container of the grid is an input form type container

I generated the code in a snippet

¿Que tengo que hacer para ver el grid.?

First of all, Thanks
(In my real application I have the pro version)

Please, try to define the sizes for your container:
“type”: “container”,
“inputHeight”: “500”,
“name”: “Grid_945”,
