Two runtime shapes share this status code, and the same endpoint can return either, so ``detail`` is typed as their union: - FastAPI's request-validation handler emits a **list** of field-level errors (built-in coercion errors and custom-validator ``ValueError``s alike). - A route that raises ``HTTPException(status_code=422, detail="...")`` for a semantic check (e.g. an invalid cron expression) emits a **string** through the HTTPException handler. example: detail: - loc: - body - endpoint msg: Value error, Endpoint must be a path, not a full URL type: value_error InternalServerErrorResponse: properties: detail: type: string title: Detail description: Human-readable error message error_id: anyOf: - type: string - type: 'null' title: Error Id description: >- Stable identifier for the specific error, present only when the error carries one error_type: anyOf: - type: string - type: 'null' title: Error Type description: Category of the error, present only when the error carries one type: object required: - detail title: InternalServerErrorResponse example: detail: Internal server error ContentStatus: type: string enum: - processing - completed - failed title: ContentStatus description: Enumeration of possible content processing statuses.
