Pull request overview
This PR aims to improve the usefulness of unhandled event error messages in EventEmitter.emit(...) by including additional context when the thrown value doesn’t have an error.message.
Changes:
- Updated the fallback “Unhandled error” message construction to include serialized error context when
.messageis unavailable. - (Formatting-only) No functional change in the closing brace at EOF.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

We're getting
Unhandled error. (undefined), which isn't super helpful. This PR retains the current logic (er.message is used when it exists), otherwise stringify the error and send it back as-is.
