        HttpStatus.ok,
        data: data,
      );
    } else {
      return AnybillResult.failure(
        type: AnybillErrorType.genericError,
        code: HttpStatus.notFound,
      );
    }
  } catch (error, stacktrace) {
    AnybillLogger.error(
      error: error,
      stacktrace: stacktrace,
      library: runtimeType.toString(),
      event: "getCachedUserQrCode",
