从OCPP CMS服务器接收TriggerMessage时出错

Question

我正在设计一个基于PyPi OCPP v1.6J的OCPP模拟器。我成功地向OCPP CMS服务器发送了Bootnotification、HeartBeat和Status通知。但是，当收到任何来自CMS服务器的消息时，我的控制台出现了错误。

我试图从CMS服务器发送TriggerMessage(心跳(，但我的模拟充电点不接受请求。它克服了一些错误。代码片段附在下面

class ChargePoint(cp):
@on(Action.TriggerMessage)
def on_trigger_message(self, requestedMessage, conectorId, **kwargs):
return call.TriggerMessagePayload(
connector_id = 1,
requested_message = "Heartbeat"
)
return call_result.TriggerMessagePayload(
status = TriggerMessageStatus.accepted

)

错误信息附在下方

此处为库的作者。

库对所有属性使用snake_case。像这样：

class ChargePoint(cp):
@on(Action.TriggerMessage)
def on_trigger_message(self, requested_message, connector_id, **kwargs):
return call.TriggerMessagePayload(
connector_id = 1,
requested_message = "Heartbeat"
)
return call_result.TriggerMessagePayload(
status = TriggerMessageStatus.accepted

)
