Hi,
we run daily integration test for our Adwords API framework. Since July 25, a couple of these tests fail because of what appears to be a change in returned error codes.
Specifically, we try to attach a bidding strategy to an adgroup (which was possible up to v201705, but disallowed from then on), and check whether the returned error is
CANNOT_ATTACH_BIDDING_STRATEGY_TO_ADGROUP (
link to reference). A second test attaches a bidding strategy to an AdGroupCriterion, which we expect to similarly fail with an
CANNOT_ATTACH_BIDDING_STRATEGY_TO_ADGROUP_CRITERIA (
link).
Both of these operations now return an OPERATION_NOT_PERMITTED_FOR_CAMPAIGN_TYPE error, which seems a bit confusing as the campaign in question is a regular search campaign.
Can we expect this new error type to stay going forward, or is it an oversight that will be rolled back?
Thanks for any feedback and best regards,
Dorian
