Worked on the stytchauth/stytch-node repository to deliver a feature enhancing error reporting within the Node SDK. Expanded the SDK’s error handling by implementing passthrough support for StytchError.error_details, allowing detailed error context to be propagated throughout the application. Updated the TypeScript type definitions to broaden error_details to accept any type, supporting nested error maps for more granular and actionable error information. This technical approach, using both JavaScript and TypeScript, improved the SDK’s debuggability and enabled faster issue resolution for integrated applications. The work focused on robust SDK development and type system enhancements to address real-world integration challenges.
