Coin Metadata can not be retrieved

Question from TG:

Sui Testnet RPC cannot fetch coin metedata?

curl --location '[https://fullnode.testnet.sui.io:443/](https://fullnode.testnet.sui.io/)' \ --header 'Content-Type: application/json' \ --data '{ "jsonrpc": "2.0", "id": 1, "method": "suix_getCoinMetadata", "params": [ "0xaf9ef585e2efd13321d0a2181e1c0715f9ba28ed052055d33a8b164f6c146a56::tusdt::TUSDT" ] }' returns "jsonrpc": "2.0", "result": null, "id": 1 }

The coin metadata creation is about a year old for that specific coin. The public RPCs don’t hold historical data that old. You would need to use an archival node or indexer for this request.
