fix in get_account_hierarchy

[CefBoud]

I had the same error mentionned in #441 using code based on examples/account_management/get_account_hierarchy.py.

Error with message "User doesn't have permission to access customer. Note: If you're accessing a client customer, the manager's customer id must be set in the 'login-customer-id' header. See https://developers.google.com/google-ads/api/docs/concepts/call-structure#cid".

The error occurs in the client.get_service("GoogleAdsService").search method because the client doesn't have a login_customer_id .

Assigning the seed_customer_id (which is part of the accessible customers) to GoogleAdsClient that generates GoogleAdsService worked for me.

for seed_customer_id in seed_customer_ids:
        client.login_customer_id = str(seed_customer_id)
        googleads_service = client.get_service("GoogleAdsService")

No need to convert this to a str as it's already defined as such by argparse here

Seems like the first googleads_service initialization on line 43 can be removed, then line 79 can be updated to use customer service:

customer_id = customer_service.parse_customer_path(
    customer_resource_name
)["customer_id"]

The changes here fixed the example for me. Previously, I was getting "User doesn't have permission to access customer."

The final patched code:

for seed_customer_id in seed_customer_ids:
    client.login_customer_id = seed_customer_id
    googleads_service = client.get_service("GoogleAdsService")

using @BenRKarl's suggested change as well (customer_service.parse_customer_path above)
