从OCPP CMS服务器接收TriggerMessage时出错

Question

正在设计一个基于PyPi的OCPP v1.6J的OCPP模拟器。我成功地向OCPP CMS服务器发送了启动通知、HeartBeat和状态通知。但是当从CMS服务器收到任何消息时，iam会在我的控制台中出现错误。

我试图给TriggerMessage (心跳)从内容管理系统服务器，但我的模拟收费点是不接受的请求。它通过一些错误。下面附上了代码片段

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
            
        )

错误信息附在下面

这里是库的作者。

该库对所有属性都使用snake_case。如下所示：

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
            
        )
