Inquiry Regarding Missing 'results' Field in API Response for searchSearch

[Van Hiep Ta]

Hi team,

I am reaching out regarding an issue we encountered when integrating with the Google API services, specifically with the searchSearch and get customizer attribute endpoints.

When we send a request, we encounter the following error:

JsResultException(errors: List((, List(JsonValidationError(List('results' is undefined on object. Available keys are 'fieldMask', 'requestId', 'queryResourceConsumption'), List())))))

You can check "requestId":"mKe3nLQD7u3ShYhri5-JQg"

Based on our investigation, it appears that the API response is missing the results field, which is causing the deserialization to fail.

Could you please confirm:

• Under what circumstances might the results field be omitted from the response?

• Is there an updated API specification or behavior we should be aware of?

• How should we handle such cases properly on the client side?

We would greatly appreciate your guidance or any suggestions for resolving this issue.
Please let me know if you need more information about our request payload or system setup.

Thank you very much for your support!

Hi,

Thank you for reaching out to the Google Ads API support team.

I understand that you are getting empty results when you try a query using the customizer_attribute resource. This would mean that you do not have data in that resource. I have checked if the data is present in your Google Ads UI account, but found that there is no data there as well and this is the reason you are getting empty results. I have attached the Google Ads UI screenshots for your reference. I hope this resolves your issue.

Thanks,

Is this a recent change in the response shape when there is no data? We have a recurring job that just recently started failing over the weekend because of a type error. It asserted that there would be a results key in the response data, but the response no longer always has results key present.

I experienced the same change.

In REST calls I made using googleAds:searchStream that returned no results. For these queries, up until Fri, 25 Apr 2025 15:26:47 GMT it returned a JSON response of an empty array "[]". Starting at Fri, 25 Apr 2025 15:41:14 GMT, the response changed. Instead I received a JSON response with the fieldMask, requestId and queryResourceConsumption keys, but no results key. Was this an expected change and if so, where is this documented? I experienced it on v18 so it was not merely changed on the newer API versions of 19 or 19.1.

Because the change was unexpected, it broke some code that anticipated the earlier format of the response.
