detail.rows() rejected for row "{key}": {error}

Warnings reference › detail.rows:failed

Identifier

detail.rows:failed

Raised by

The grid (rendering)

Since

1.4.0

What happened

The detail.rows() function returned a promise that rejected, so no rows were loaded for that detail panel. The nested grid stays empty; the parent grid is unaffected.

The fix

The rejection's message is quoted in the line. detail.rows() is called per expanded row, so a failure is usually a per-row fetch.

The smallest fix

detail: { rows: (row) => fetch(`/api/lines/${row.key}`).then((r) => r.json()) }
