Hello,
I want to create a smart display campaigns iterator, but it returns me an error. It's someting like this:
function main(){
var sdcIterator = AdsApp.campaigns.withCondition("AdvertisingChannelSubType = 'DISPLAY_SMART_CAMPAIGN'").get();
}
It throws the following error:
Exception: Value DISPLAY_SMART_CAMPAIGN is invalid. Please check spelling and casing and verify the value's type matches the field's type.
But this value is picked from:

If I try another value (eg: DISPLAY_GMAIL_AD) it works
How Can I do that with smart display campaigns?
