是想调用合约里的一个方法，之前试过调用另外一个方法可以，但这次调用就出错了，提示：

Could not look up name 'XXXXXXX' because web3 is not connected to mainnet

我搜了下是跟w3.eth.default_account有些关系？但还是搞不明白

附上这个函数的abi：

{
        "inputs": [
            {
                "internalType": "address",
                "name": "user",
                "type": "address"
            },
            {
                "internalType": "address",
                "name": "career",
                "type": "address"
            },
            {
                "internalType": "address",
                "name": "payAddr",
                "type": "address"
            },
            {
                "internalType": "uint256",
                "name": "tokenId",
                "type": "uint256"
            },
            {
                "internalType": "uint256",
                "name": "price",
                "type": "uint256"
            },
            {
                "internalType": "string",
                "name": "name",
                "type": "string"
            }
        ],
        "name": "sellPlayer",
        "outputs": [],
        "stateMutability": "nonpayable",
        "type": "function"
    }

有大佬知道是怎么回事吗？谢谢！

Update: 我看了下报错的函数，最终发现是在这里报错的：

我打印了w3.net.version看了下，发现就是chain id，代码这里要是1才可以，但chain id怎么改啊？？

麻烦懂的大佬给下解答，谢谢！
