config.fields names `{field}`, which is not a column on the bound grid - check it against the grid's column ids.

kpi:no-column::*

Raised by

Since

1.54.0

What happened

One of the names in fields is not a column of the bound grid. Nothing is projected for it, so any tile filter or custom aggregation that reads it sees undefined. The rest of fields is projected normally.

The fix

Correct the name, or drop it. Column *ids* are what the panel matches against, not header titles.

The smallest fix

createKPI(el, { grid, fields: ['region'], tiles });
