This Facebook Lead Ads step hit an error

Error while hydrating data from Facebook Lead Ads: The app returned "Unsupported get request. Object with ID xxxxxxxxxxxx does not exist, cannot be loaded due to missing permissions, or does not support this operation. Please read the Graph API document 

I saw conversations where the question have been asked 1 month ago but the only answer from Zappier’s team is to contact support….

Does anyone have a manual solution to this problem ?
