ERROR

media_type=MEME is returning all media_type in contrast media_type IMAGE ,VIDEO,NONE are working correctly

probably, issue can be due to change in definition in the Ad Library definition of IMAGE , MEME see the attachment above

How did i found this error,

i was sceptical when i found number of ads in media_type=ALL and media+type=MEME to be same for same range of date

MEME are images not videos but the api call returned an entry with Library ID: 334616886342598 https://www.facebook.com/ads/library/?id=334616886342598

when i applied filter in the GUI for Ad library
https://www.facebook.com/ads/library/?active_status=all&ad_type=political_and_issue_ads&country=IN&id=334616886342598&view_all_page_id=257916314892663&sort_data[direction]=desc&sort_data[mode]=relevancy_monthly_grouped&search_type=page&media_type=meme

i did not find the Ad with Library ID: 334616886342598

hence it was not a meme and the api call is returning wrong media_type even if the parameter passed is media_type=MEME

As the Loksabha results have come out 5 days back and winners have been decided. Those who have got the majority, already form the #government , in spite of this opposition still making negative comments and showing arrogance. The #OppositionArrogancy are comdamnable from every side. Please listen to this video carefully. I think the upper hand people should avoid the Oppositions' negative and baseless remarks."
