Hi,
Thank you for reaching out to the Google Ads API support team.
Upon reviewing your query, I understand that you would like to search for ad_groups with no labels in your account. To search for ad_groups with no labels in Google Ads Query Language (GAQL), you need to use the CONTAINS NONE operator. This operator allows you to find items where a specified field does not contain any of the provided values.
Please specify (' ') for the CONTAINS NONE operator, which indicates that the ad_group.labels field should not contain any values. Additionally, I have observed that you are using ad_group_ad.ad.id, which is not a supported resource field in the ad_group. I would suggest you refer to this document to know more about the supported resource fields in the ad_group.
If you need further assistance, please provide the uncropped UI screenshot of the report of which you're trying to retrieve via the API.
