尝试从 Matic Polygon Testnet 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
