ABP Exception Handling Skill

ABP exception handling standardizes API error responses by formatting RemoteServiceErrorResponse payloads to include error codes, details, and validation errors. Implementing interfaces like IHasErrorCode and IHasErrorDetails ensures API consumers receive safe, consistent JSON errors.

HTTP status mapping in ABP assigns specific status codes to exceptions using default framework rules. You can override these defaults and map custom business exceptions to specific HTTP statuses by configuring AbpExceptionHandlingOptions with custom exception mappers.

Validation errors in ABP API responses are structured using AbpValidationException to generate a detailed validationErrors array. This mechanism provides actionable field-level validation feedback within the standard RemoteServiceErrorResponse payload.

ABP exception logging is controlled using IHasLogLevel and IExceptionWithSelfLogging to capture contextual data without exposing sensitive stack traces. This approach ensures secure logging behavior while preventing internal failure leakage in production environments.

ABP Framework API exception responses support localized messages to provide user-friendly error output. By configuring the exception handling pipeline, you can return translated error details safely within the RemoteServiceErrorResponse payload structure.

Custom exception mappers in ABP Framework are implemented by configuring AbpExceptionHandlingOptions to intercept specific exceptions. This approach overrides default exception-to-status mapping to return tailored HTTP codes and safe error payloads for business exceptions.
