google.api_core.exceptions.MethodNotImplemented: 501 GRPC target method can't be resolved

[fespinasse]

Describe the bug:

Hello,

I'm new at Google API, and I was trying to test KeywordPlanIdeaService.
I try to follow the example provided in your doc (https://developers.google.com/google-ads/api/docs/keyword-planning/generate-keyword-ideas?hl=fr#python), removing stuff about which I don't know values to give.

But I get this error:
google.api_core.exceptions.MethodNotImplemented: 501 GRPC target method can't be resolved.

Steps to Reproduce:

Here is the final code:

from google.ads.googleads.client import GoogleAdsClient
import json

class ApiGoogleAds:
CREDENTIALS_FILE = "config/google-ads-credentials.json"
API_KEY = "..." # Api_key in google console for public data
credentials = None
client = None

def __init__(
    self,
):
    with open(self.CREDENTIALS_FILE, "r") as outfile:
        self.credentials = json.load(outfile)

    self.client = GoogleAdsClient.load_from_storage(self.CREDENTIALS_FILE)

def get_keyword_ideas(self, keywords: str = "", url: str = ""):
    keyword_plan_idea_service = self.client.get_service("KeywordPlanIdeaService")
    keyword_plan_network = (
        self.client.enums.KeywordPlanNetworkEnum.GOOGLE_SEARCH_AND_PARTNERS
    )

    if not (keywords or url):
        raise ValueError(
            "At least one of keywords or page URL is required, "
            "but neither was specified."
        )

    request = self.client.get_type("GenerateKeywordIdeasRequest")
    request.customer_id = self.credentials["login_customer_id"]
    request.include_adult_keywords = False
    request.keyword_plan_network = keyword_plan_network

    if keywords and url:
        request.keyword_and_url_seed.url = url
        request.keyword_and_url_seed.keywords.extend(keywords)
    elif keywords:
        request.keyword_seed.keywords.extend(keywords)
    elif url:
        request.url_seed.url = url

    keyword_ideas = keyword_plan_idea_service.generate_keyword_ideas(
        request=request
    )

    for idea in keyword_ideas:
        competition_value = idea.[keyword_idea_metrics.competition.name](http://keyword_idea_metrics.competition.name/)
        print(
            f'Keyword idea text "{idea.text}" has '
            f'"{idea.keyword_idea_metrics.avg_monthly_searches}" '
            f'average monthly searches and "{competition_value}" '
            "competition.\n"
        )

if name == "main":
...

And then, my testing script :

python -m scripts.test_google_ads

from crawlers.api.api_google_ads import ApiGoogleAds

apiAds = ApiGoogleAds()
apiAds.get_keyword_ideas(keywords="bottes en cuir")

Expected behavior:

No error, or clear params/config error if I missed some params.

Client library version and API version:
Client library version: Python 3.9.18
Google Ads API version: google-ads==21.3.0

Request/Response Logs:

And when I run it, I have the following exception:

The above exception was the direct cause of the following exception:

I tried to look a bit if I found similar troubles reports, but either it's not matching mine, or I misunderstand things...

Could you please help me a bit ?
Sorry if my knowledge level about Google tools, even just development skills, are not very good, or even my english level.

Anything else we should know about your project / environment:

Thanks for the help you will provide.
