createAI needs a Lattice grid instance to ground on (grid.statistics/grid.rows). Pass the grid returned by createGrid or createHeadlessGrid.

1.42.0

What happened

createAI() was called with something that is not a grid, or with a grid that exposes neither statistics nor rows. The AI layer grounds every figure it produces in numbers it reads from the grid, so without one it has nothing to ground on: the controller is still returned, but narratives and answers will have no data behind them.

The fix

Pass the object returned by createGrid or createHeadlessGrid as the first argument.

The smallest fix

const grid = createGrid(el, config);
const ai = createAI(grid, { ask });
