Summary by CodeRabbit

• Bug Fixes
  • Corrected type declarations so WebSocket proxy factories can return no handler. This avoids type errors when a proxy factory conditionally provides a handler, while preserving support for factories that return one.

Walkthrough

The private webSocketProxies field’s element type now allows a factory to return RequestHandler or undefined. The external WebSocket test sets the connection origin to the dev-server URL and rejects its setup promise when the socket emits an error.

Priority: ⬇️ Low

Merge Risk: ⚪ Minimal · up to 48486

The generated type matches the handled runtime behavior, and the WebSocket test still checks the echoed message while rejecting setup errors. No actionable merge risk is evident.
