createStat needs a document; it draws DOM.

Warnings reference › stat.document

Identifier

stat.document

Raised by

The grid (rendering)

Since

1.10.0

What happened

The container resolved, but it belongs to no document and there is no global one - a detached node in a non-browser runtime. An inert handle is returned and nothing is drawn.

The fix

Create the stat in a real document. There is nothing for it to do in a headless environment; read the number from grid.statistics instead.
