Hi,
In order to determine the campaign where MUTATE_ACTION_NOT_PERMITTED_FOR_CLIENT occurs, I think that it can be determined by referring to SEARCH_EXPRESS and DISPLAY_EXPRESS of AdvertisingChannelSubType.
However, when getting information on the corresponding campaign by GET operation, AdvertisingChannelType is UNKNOWN, AdvertisingChannelSubType is not returned, so we can not determine the campaign where MUTATE_ACTION_NOT_PERMITTED_FOR_CLIENT occurs.
What should I refer to in order to identify Adwords express campaigns?
The ID of the campaign currently having problems is as follows.
CampaignId 1416515981
The currently used API version is v201802.
Best regards,
Inoue
