*Hi everyone,*
I'm currently working with the Google Ads API v18 to create a Demand Gen
Video Responsive Ad, and I've run into a confusing issue when trying to
initialize the DemandGenVideoResponsiveAdInfo.
*When I attempt to initialize the object like this:*
DemandGenAdInfoClass = client.get_type("DemandGenVideoResponsiveAdInfo")()
*I get the following error:*
Message must be initialized with a dict:
google.ads.googleads.v18.common.DemandGenVideoResponsiveAdInfo
*This suggests the API expects a dictionary rather than a protobuf
instance. However, if I try the alternative: *
DemandGenAdInfoClass = client.get_type("DemandGenVideoResponsiveAdInfo")
*and then use:*
demand_ad = DemandGenAdInfoClass()
So I’m stuck between two approaches — one gives a dict initialization
error, and the other says the object is not callable.
Could anyone please clarify the correct way to instantiate and populate
DemandGenVideoResponsiveAdInfo in v18?
Share my code.
Any working code example would be greatly appreciated.
Thanks in advance!
