getNFTTransfers returns 0 results when etherscan shows transactions

When I run this http request on one of my wallets, the result is an empty array although there have been several NFT transfers beeing made from this account. Why is that?

It could happen that we didn’t index that particular nft contract. You can add it to sync in case that it is not already synced. You can try to list the token ids from that specific contract to see if it works.
