错误: 'coroutine' object has no attribute 'json'

Replied message is: {
    "acquisitionType": "",
    "data": {
        "errorCode": "000"
    },
    "deviceId": "",
    "id": "",
    "stationId": "",
    "timestamp": "1623115085461",
    "type": "report",
    "version": "1.0"
}

碰到说这个断言有问题的

但是我看Request的样例里面是这么写的，我想要的效果就是能够判断JSON内的这个error code字段

assert reply.json()['data']['errorCode'] == "000"
AttributeError: 'coroutine' object has no attribute 'json'
