python 脚本中的 ListRecommendationsRequest 构造函数错误

Question

我正在尝试使用 python3.7 脚本准备 VM 大小调整建议报告 我的代码如下：

导入日期时间

import logging
from google.cloud import bigquery
from google.cloud import recommender
from google.cloud.exceptions import NotFound
from googleapiclient import discovery

def main(event, context):
 client = recommender.RecommenderClient()
 recommender_type = "google.compute.instance.MachineTypeRecommender"
 projects=list_projects() #This gives list of projects
 # I hard-code the zones below:
 zones = ["us-east1-b","us-east1-c","us-east1-d","us-east4-c","us-east4-b","us-east4-a"
        ,"us-central1-c","us-central1-a","us-central1-f","us-central1-b"
        ,"us-west1-b","us-west1-c","us-west1-a"]

 for zone in zones:
            parent = client.recommender_path("my-project", zone, recommender_type)
            for element in client.list_recommendations(parent): #In this line I am getting this error and these are logs

****Parent****   projects/my-project/locations/us-east1-b/recommenders/google.compute.instance.MachineTypeRecommender
Traceback (most recent call last):
  File "main.py", line 187, in main
    x=list(client.list_recommendations(parent))
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/google/cloud/recommender_v1/services/recommender/client.py", line 734, in list_recommendations
    request = recommender_service.ListRecommendationsRequest(request)
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/proto/message.py", line 441, in __init__
    raise TypeError(
TypeError: Invalid constructor input for ListRecommendationsRequest: 'projects/my-project/locations/us-east1-b/recommenders/google.compute.instance.MachineTypeRecommender'

During handling of the above exception, another exception occurred:

projects/my-project/locations/us-east1-b/recommenders/google.compute.instance.MachineTypeRecommender 是传递给 list_recommendations 函数的参数。当我得到这个时，我不确定构造函数中有什么问题：ListRecommendationsRequest

的构造函数输入无效

我是新手 google api。有人可以帮忙吗？谢谢

我检查了我这边的代码，调用该方法时似乎是语法错误。根据 library documentation 第一个参数应该是 请求对象 或 None 并且必须传递父参数按名字。如下更改行我没有错误：

client.list_recommendations(parent=parent)
