config.fields must be an array of column names; ignoring it.

1.54.0

What happened

fields was present but was neither a string nor an array, so it was ignored entirely. fields names the extra grid columns a bound panel projects onto its rows; with it ignored, a tile filter that reads one of those columns sees undefined - which is how a panel ends up showing a confident zero.

The fix

Pass an array of column ids (a single id as a plain string is also accepted).

The smallest fix

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