Such an error may come up when exporting data from Yandex.Direct and Facebook.
In the case of Yandex.Direct, Smart banners, Search banners or Dynamic campaigns may cause this error. For now, the info about them is unavailable because of API Yandex.Direct. Yandex is going to support such ads in the near future. However, there's no definite implementation timeline.
In the case of Facebook, this error may occur because of some restricted content (e.g. country or age restrictions).
As there's no possibility to import image ad cost data automatically as of yet, we suggest you use OWOX BI Data Upload Add-on to send cost data manually.
