Worked on the workos-node repository to enhance backend error handling by introducing an improved ConflictException. This update added an optional code property, providing richer context for conflict errors and enabling more consistent handling across client integrations. The feature was implemented in TypeScript with a focus on robust backend development and error management practices. By exporting the ConflictException for broader reuse, the work established a foundation for more efficient debugging and clearer error visibility throughout the codebase. Collaboration with other contributors ensured the change set addressed cross-team needs, prioritizing internal reliability and developer experience during the month’s focused engineering efforts.
