Hi Naomi,
The error indicates that the image asset and video asset resource names are not formed correctly. You will need to use the Asset resource as part of the resource name. Please find the code snippet below:
AdVideoAsset video = AdVideoAsset.newBuilder()
.setAsset(StringValue.of(ResourceNames.asset(customerId, 6544940770L)))
.build();
AdImageAsset image = AdImageAsset.newBuilder()
.setAsset(StringValue.of(ResourceNames.asset(customerId, 27398859L)))
.build();
AppAdInfo appadinfo = AppAdInfo.newBuilder()
.addDescriptions(text)
.addAllHeadlines(ImmutableList.of(text, text1))
.addAllDescriptions(ImmutableList.of(description))
.addAllImages(ImmutableList.of(image))
.addAllYoutubeVideos(ImmutableList.of(video))
.build();
Please give this a try and let me know if you have any questions.
Thanks,
Bharani, Google Ads API Team
