unrelated, an example with IPFS folder: https://etherscan.io/address/0xF1F3ca6268f330fDa08418db12171c3173eE39C9#readContract I get ipfs://QmSknFJz1Z16xKGBJPF41DPsCzyzCYqBD8ZmVmnyaN1Vw4/4
for uri(4)
Maybe that 1001 was translated to hex and it tries to access: https://sphji7fradbe.moralishost.com/00000000000000000000000000000000000000000000000000000000000003e9.json
that is not found.
and maybe the json that you added is not valid json either:
{
"description": "Common series car one of its kind",
"image": "https://ipfs.moralis.io:2053/ipfs/QmXGWtScN5fE3TWQH5dQeUnit6DVyHzepRRKndJYKGqwko",
"name": "COMMON SERIES: UNDERDOG_DRIFTER",
"attributes": [ ... ],
}
because it has that line with "attributes": [ ... ],
