Worked on enhancing error handling within the aws/aws-advanced-nodejs-wrapper repository by improving how AWS errors are managed and propagated. Focused on preserving the original source error as the 'cause' in AwsWrapperError, this change allows for richer debugging and more effective root-cause analysis when AWS-related failures occur. The update ensures that detailed error information is retained throughout AWS SDK interactions, leading to clearer logs and faster troubleshooting. Implemented in TypeScript with a focus on robust error handling, the solution maintained backward compatibility while increasing observability and reliability for AWS operations, addressing a key pain point in debugging complex cloud workflows.
