I'm building a Kotlin backend with Ktor and want to set up centralized exception handling across all endpoints. Could you write a Ktor configuration function using StatusPages that catches common runtime errors (like invalid request payloads, bad arguments, missing entities, and auth failures) and maps them to a consistent JSON error wrapper? Please show both the error configuration code and the standard API response data model.
| Checked | Without skill | With skill |
|---|---|---|
| Defines an ApiResponse data model containing success, data, and error fields. | Missed | Passed |
| Configures StatusPages exception handlers using ApiResponse.error for response wrapping. | Missed | Passed |
