Hi,
The error
INVALID_ID is encountered when you are referencing the ID of an entity from a different account or the entity specified has already been removed. To see if the ad group
(2045191148) you are targeting is still existing, you could run the
AdGroupService.get() and see if the ad group you are targeting is returned. If it is not returned after running the service, it is most likely that the ad group Id you are targeting to is from a different account.
However, to further investigate this, could you provide the complete SOAP request and response logs with the clientCustomerId specified when you encountered the error? You may provide the requested information via Reply privately to author.
