For some NFTs, the metadata property is null for some reason. Also, the is_valid is 0 and syncing is 2 which I presume is “still” syncing or there is some problem syncing the data.
{
"metadata": null,
"is_valid": 0,
"syncing": 2
}
I wonder how long will Moralis reattempt to resync or reindex invalid NFT data?
