tabs: config.createHeadlessGrid must be the headless grid factory (a function); got {type}. It is ignored, so a tab that has never been activated shows no badge until it is.

1.59.0

What happened

createHeadlessGrid was supplied but is not a function, so it was ignored entirely. It is an optional dependency and never fatal, but the symptom of its absence - badges that only appear once a tab is clicked - looks like a defect, which is why a wrong type is reported rather than passed over.

The fix

Pass the factory itself, not its module namespace and not a string.

The smallest fix

import { createHeadlessGrid } from '@toclocoinc/lattice-grid';
createTabs(el, { createGrid, createHeadlessGrid, tabs });
