tokenOfOwnerByIndexERC721 时执行恢复错误

Question

尝试从 Matic Polygon 测试网帐户按索引获取 tokenId 时出错

"maticProvider": "https://polygon-mumbai.infura.io/v3/<project_id>",
"parentProvider": "https://goerli.infura.io/v3/<project_id>"

代码：

const network = new Network(config.network, config.version);
// TODO do somthing about the unused
const MaticNetwork = network.Matic;
const MainNetwork = network.Main;

const matic = new Matic({
  maticProvider: config.maticProvider,
  parentProvider: config.parentProvider,
  rootChain: MainNetwork.Contracts.RootChain,
  withdrawManager: MainNetwork.Contracts.WithdrawManagerProxy,
  depositManager: MainNetwork.Contracts.DepositManagerProxy,
  registry: MainNetwork.Contracts.Registry
});

matic.tokenOfOwnerByIndexERC721(
    '<accountAddress>',
    '<tokenAddress>',
     0, {
       from: '<accountAddress>',
       gas: 150000
     })
     .then(console.log)

这会引发错误

请帮忙！

发现问题。

合约需要扩展ERC721Enumerable 以在其中实现tokenOfOwnerByIndex。
