Question

我有 python azure 函数，它根据 Iothub 事件触发器从 azure IotHub 读取数据。下面是我的代码

def main(events: List[func.EventHubEvent]):
    try:
        keyfunc = lambda x: (x.iothub_metadata['connection-device-id'])
        data = sorted(events, key=keyfunc)
        for k,v in itertools.groupby(data,keyfunc):
            dictionarylist = [dict(dic, deviceid=k) for dic in [json.loads(x.get_body().decode('utf-8')) for x in v]]
            insertdata(deviceid=k,datalist=dictionarylist)
            insertforprocessing(deviceid=k,datalist=dictionarylist)
    except Exception as e:
           print(e)

我不断收到以下错误并且没有处理数据。我不知道如何解决这个问题。
