Solutions

1. Increase the column's maximum string length to at least the maximum street-address length, or use a different generator.

When it happens

Trigger: Using the street-address generator on a column shorter than the longest street address.

Common situations: Short varchar for addresses; raise to maxStreetAddressLength.
