source.mode "derived": unknown `statistics.fn` "{fn}". Known: {list}. Every *single-column* statistic is reached through `select` instead, e.g. `select: { p95: { of: 'amount', fn: 'p95' } }`.

What happened
statistics names the *relational* statistics - the ones whose answer is a table of relationships between columns or datasets. The name given is not one of them, so nothing is produced. A single-column statistic is not here at all; it is a select entry.
The fix
Use one of the relational statistics listed in the message, or reach a single-column statistic through select.
