How to use the @mojaloop/event-sdk.EventStateMetadata function in @mojaloop/event-sdk

const fspiopError = ErrorHandler.Factory.createFSPIOPError(ErrorHandler.Enums.FSPIOPErrorCodes.CLIENT_ERROR)
      await Kafka.proceed(Config.KAFKA_CONFIG, params, { consumerCommit, fspiopError: fspiopError.toApiErrorObject(Config.ERROR_HANDLING), eventDetail, fromSwitch })
      throw fspiopError
    }
    // ============================================================================================
    Util.breadcrumb(location, { path: 'validationPassed' })
    Logger.info(Util.breadcrumb(location, `callbackMessage--${actionLetter}4`))
    message.value.content.payload = TransferObjectTransform.toFulfil(transfer)
    await Kafka.proceed(Config.KAFKA_CONFIG, params, { consumerCommit, eventDetail, fromSwitch })
    histTimerEnd({ success: true, fspId: Config.INSTRUMENTATION_METRICS_LABELS.fspId })
    return true
  } catch (err) {
    histTimerEnd({ success: false, fspId: Config.INSTRUMENTATION_METRICS_LABELS.fspId })
    const fspiopError = ErrorHandler.Factory.reformatFSPIOPError(err)
    Logger.error(`${Util.breadcrumb(location)}::${err.message}--G0`)
    const state = new EventSdk.EventStateMetadata(EventSdk.EventStatusType.failed, fspiopError.apiErrorCode.code, fspiopError.apiErrorCode.message)
    await span.error(fspiopError, state)
    await span.finish(fspiopError.message, state)
    return true
  } finally {
    if (!span.isFinished) {
      await span.finish()
    }
  }
}
