    - In cascade cancel scenarios, error description includes complete cancel link, quickly locating the first-hop service that actively cancels
    - Error description includes specific error scenarios and corresponding unique error codes
    - Unified and convenient cancel error handling method, eliminating the need for cumbersome string matching
