I am using react-native-whatsapp-sticker and modified it according to a repo react-native-dynamic-whatsapp-sticker.Those modules have not get updated since 2-3 years so the repo does not contains code for animated stickers. So I compered my module with WhatsApp sample app and made changes accordingly.There is no errors building the apk and stickers get added if I set animated sticker pack to false. But setting "animated_sticker_pack"=true and then adding sticker pack, WhatsApp show error as "there is problem with this pack...".
