I'm trying to get information regarding a transaction from testnet, so I'm sending a JSON request to monero-wallet-rpc:
{"id":"0","jsonrpc":"2.0","method":"get_transfer_by_txid","params":"0e2a8c486d5a57fe8d48ba3e7ca07ad1735eb1f3026e3d1021ca7ee3238fe7db"}
But I'm receiving:
{"error":{"code":-8,"message":"Transaction ID has invalid size: "},"id":"0","jsonrpc":"2.0"}
What does the error mean?
