Hi,
I created an advertisement through the API with two titles and
descriptions, and then I called the modify advertisement API, but i got an
error "Field 'ad.app_ad.images' cannot be modified by 'UPDATE' operation."
Is this because my FieldMask is wrong? Or is it that the interface does not
support modifying creatives?
The FieldMask I filled in is "Paths: []string{'ad.app_ad.images'}"
Looking forward to your reply.
Below is my request body and response body：
request：&services.MutateAdGroupAdsRequest{state:impl.MessageState{NoUnkeyedLiterals:pragma.NoUnkeyedLiterals{},
