Getting error "The image ad extension's media id is invalid." while adding Images element instead of Mediaid's in bing ads image extension

Answer 1

Note, if you are not in the Multi-Image Ad Extensions pilot you must use the ImageMediaIds element. Please check the reference docs and let me know if you have any additional questions.

Answer 2

Dear EricUrban-MSFT,
I try to add an image extension via Bing Ads API in Python.
In my opinion, I care about the documentation rules. But I am getting below error.
Could you help me to understand what is wrong or missing?

My code :

value = values["values"][0]  
ad_extensions = self.service.factory.create("ArrayOfAdExtension")  
asset_links = self.service.factory.create("ArrayOfAssetLink")  
image = set_elements_to_none(self.service.factory.create("ImageAdExtension"))  
image.ImageMediaIds = {"long": [value["asset_remote_id"]]}  
image.AlternativeText = value["image_name"]  
image.DisplayText = value["image_name"]  
image.FinalUrls = {"string": value["image_url"]}  
image_asset = set_elements_to_none(self.service.factory.create("ImageAsset"))  
asset_link = set_elements_to_none(self.service.factory.create("AssetLink"))  
image_asset.Id = value["asset_remote_id"]  
image_asset.SubType = "LandscapeImageMedia"  
image_asset.Type = "ImageAsset"  
asset_link.Asset = image_asset  
asset_links.AssetLink.append(asset_link)  
image.Images = asset_links  
ad_extensions.AdExtension.append(image)  
response = self.service.AddAdExtensions(  
                   AccountId=self.account_id,  
                   AdExtensions=ad_extensions,  
)  
      

Error message:
