A lookup that required one object found none.

The criteria are on [`ObjectNotFoundError.query`](/en/ts/latest/reference/errors-objectnotfounderror-query/) as they were written,
and rendered into the message. Raised by the strict lookups; the lenient
ones return [`undefined`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/undefined) instead.
