The error message has indicated benchmark_report_count doesn't exist. So you need to remove it from list of fields.

[Nandini]

But we are not requesting for any specific field. We're just using this function:
Campaign.fetchById(facebookCampaignId, adAccount.getContext())
in the SDK there is a field called benchmark_report_count. And this same function is working in v14.0

Could you check if you are using the latest version (15.0.2) of the SDK? The field benchmark_report_count has been removed from the class. link
