我正在尝试获取视频字段，但即使 API 在字段中请求，API 也不会返回列。
我要获取的字段是：video_p25_watched_actions, video_p50_watched_actions, video_p75_watched_actions, video_p100_watched_actions.
我的 API 请求参数如下：
request.AddParameter("export_columns", "['actions:video_view','actions:video_view:video_p25_watched_actions','adgroup_name','date_start','date_stop','campaign_group_name','campaign_name','adgroup_id','impressions','clicks','spend','actions:like','actions:offsite_conversion','actions:receive_offer','actions:rsvp','actions:leadgen.other','actions:link_click','actions:comment','actions:post','actions:post_engagement','social_impressions']");
request.AddParameter("fields", "['ad_name','campaign_name','adset_name','ad_id','impressions','clicks','spend','actions','social_impressions','video_p25_watched_actions','video_p50_watched_actions','video_p75_watched_actions','video_p100_watched_actions']");
request.AddParameter("filtering", "[{ 'field':'ad.impressions','operator':'GREATER_THAN','value':0}]");
如果我缺少任何东西，请帮助我。
