Hi,
I am trying to use the examples of the updates operations in Google Ads API Ruby Client Library.
The example of update a campaign works for me, but the others examples for update a expanded text ad, ad group or keyword do not work and i get GoogleAdsError.
The error always happens in the mutate line, for example in update ad "response = ad_group_ad_service.mutate_ad_group_ads(customer_id.to_s, [operation])"
Thanks, Javier.
