class NotFound(AppError):
    pass


class ValidationError(AppError):
    pass


def categorise(exc: Exception) -> str:
    try:
        raise exc
    except Exception:
        return "generic"
    except AppError:
        return "app"
    except NotFound:
        return "not-found"
    except ValidationError:
        return "validation"


print(categorise(NotFound("user 42")))
print(categorise(ValidationError("schema bad")))
