Hello Google Ads API Support Team,I am encountering an Unrecognized field in the query error when attempting to select the campaign.feed_types field in a Python script using API version v22.
The field is listed in the v22 documentation as available under the campaign resource, but my request consistently fails. I have verified that my client library is up to date and that I am targeting the correct API version in my service call.
Here are the technical details:
API Version: v22
Client Library: Python
Error Message: (Please insert the full, exact error message here, including any fieldPathElements or requestId if available in your logs)
Query used:
SELECT
campaign.feed_types,
FROM campaign
WHERE
campaign.advertising_channel_type IN ('PERFORMANCE_MAX', 'SHOPPING')
Relevant Python Code Snippet:
def ShoppingCampaigns(ga_client,customer_id):
query = """
SELECT
campaign.feed_types
FROM campaign
WHERE
campaign.advertising_channel_type IN ('PERFORMANCE_MAX', 'SHOPPING')"""
# Instantiate dataframe
df = pd.DataFrame()
# instantiate service
ga_service = ga_client.get_service("GoogleAdsService",version="v22")
# Issues a search request using streaming.
stream = ga_service.search_stream(customer_id = customer_id, query = query)
for batch in tqdm(stream):
if 'results' in MessageToDict(batch._pb):
df = pd.concat([df,pd.json_normalize(MessageToDict(batch._pb),record_path=['results'])])
return df
