How can an interceptor add a timeout to slow handlers?

1Set @Timeout() on the DTO
✓Correct answer: next.handle().pipe(timeout(5000), catchError(...)) and map the timeout to RequestTimeoutException
3Interceptors can't affect timing

Explanation

This stops waiting for the result, but the underlying work keeps running unless you also cancel it (for example with an AbortSignal).
