DS Express Errors (centralizing errors library) — v1.9.2 Release Notes August 16, 2026

v1.9.2 – August 16, 2026

This release improves production error responses, strengthens JWT error handling, and fixes the TypeScript type for needMappers.

• Fixed excessive production response sanitization in Zod, Joi, express-validator, Mongoose, Prisma, and Sequelize mappers
• Added separate JWT mapper handling to prevent sensitive JWT error details from being exposed in production
• Fixed the TypeScript type for needMappers
• Updated README.md documentation
• Expanded tests for production-safe mapper responses

What does it mean?

Starting with v1.9.2, production responses from supported library mappers are more useful and informative. Previously, some mapper responses were sanitized more aggressively than necessary, which could remove details that were safe to return to API consumers.

Sensitive information is still protected where required, while development mode continues to provide additional details useful for debugging.

JWT errors are now handled separately. This provides stricter control over what information can appear in production responses and addresses a case where sensitive JWT error details could potentially be exposed.

The TypeScript definition for needMappers has also been corrected. It now uses the appropriate union type instead of being typed as a generic string[], improving type safety and editor autocomplete when configuring mappers.

Finally, the documentation has been updated to make several parts of the library clearer, including how NODE_ENV affects error responses, which errors may be thrown by the library itself, and where to find relevant configuration information.
