tokenOfOwnerByIndex()函数调用问题

付笑

调用json:
{
        "jsonrpc":"2.0",
        "method":"eth_call",
        "params":[{
                "to": "0xE125C05E771b887C702b0d4f5C5e8F933bf4AC71",
                "data": "0x2f745c59000000000000000000000000C0Bea838a7D59d4739C85C1E36943f5f6Ac7bBEB0000000000000000000000000000000000000000000000000000000000000001"
        }, "latest"],
        "id":1
}


返回结果：
{"jsonrpc":"2.0","id":1,"error":{"code":-32000,"message":"execution reverted"}}

请问返回结果为什么会出错了呢，是函数编码不对呢，还是参数不对呢？
函数tokenOfOwnerByIndex(address _owner, uint256 _index) 的编码0x2f745c59是正确的么？

Siempre

bin2hex (到字节集 (“tokenOfOwnerByIndex(address _owner, uint256 _index)”))
