I now tried some if array code on current, and it ran through and listed traits in the terminal 0,1,2,3,4,5,true and back to command prompt…

this loaded the main page NFTs! but there’s an error when I click on the NFT thumbnail. None of the rarity shows and it crashes with errors nft.rarity is not a function or nft.attributes.map is not a function If I comment out the nft rarity in the QuickStart.jsx I can get it to load the large image at the top just without any rarity info displaying.
Hi, I’ve been trying to get this script working I’ve changed out some code to deal with the new pagination and have followed along with the the attributes thread above.So I’ve added the MoralisSecret to the await inside the generateRarity function. Add updated the pagination replacing offset with the new do code block I think I found on the youtube video comments. But unfortunately still getting an error when it comes to current.push.
