Facebook graph api Facebook营销Adindsight API中的字段“位置”

我在字段放置上有错误 这不是一个国家，而是facebook受众、facebook和instagram之间的多样化。。。我的全部要求是：

    account = AdAccount('act_46605285454545442')
    ads = account.get_ads()
params = {
    'time_range': {
        'since':  "2019-06-01", 
        'until': "2019-06-26"
        }, 
    'fields': [
        AdsInsights.Field.campaign_id,
        AdsInsights.Field.campaign_name,
        AdsInsights.Field.adset_name,
        AdsInsights.Field.ad_name,
        AdsInsights.Field.spend,
        AdsInsights.Field.impressions,
        AdsInsights.Field.clicks,
        AdsInsights.Field.buying_type,
        AdsInsights.Field.objective,        
        AdsInsights.Field.actions,
        AdsInsights.Field.cpm,
        AdsInsights.Field.account_currency,
        AdsInsights.Field.placement,
     ],
    'level': 'ad',
    'time_increment': 'all_days',
}
async_job = account.get_insights_async(fields = params.get('fields'), params=params)

这给了我一个错误：位置对字段无效。据我所知，param不是字段，而是细分。听起来你把它放错地方了。但不能确定，因为您还没有发布任何其他详细信息
