thanks for reporting this issue. image_asset is a breakdown and we will need to find a way to figure out how to assign the return type for the breakdowns.

@stcheng Can you please let us know any possible ETA around the fix? Noticed not only image_asset but even body_asset also comes as json, however breakdowns like age come as string. Is there any way we can figure out which breakdowns are string and which are json? Currently checking with hitting the API manually, would like to verify the same with some documentation and https://developers.facebook.com/docs/marketing-api/insights/breakdowns does not have sample responses for all types of breakdowns.

this has been addressed in our latest release v19.0.1 with the introduction of multiple AdAsset* types support in Java.
