Subject: [PATCH] fix(type-safe-api): silence warnings for mock data generation
 for fields with pattern constraints (#892)

ReRegExp is used to generate mock data for fields with regex patterns. ReRegExp is quite noisy with
its warnings, printing directly to the console. This change silences these warnings.

Fixes #891
