Solutions

1. Widen the (min, max) range or reduce the count of unique integers requested.

When it happens

Trigger: generateUniqueInt with count larger than (max - min + 1) for the given integer range.

Common situations: Too-narrow min/max range on a unique integer column; large seed count with default range.
