Web3 错误：Geth 无法与/调用合约函数进行交易答案

【问题描述】：

我决定运行我自己的 ethereum/bsc 全节点。我下载了 geth-linux-amd64-1.1.0 并像这样运行它： geth --syncmode "full" --http --http.port 8545 --http.corsdomain "*" --http.addr "127.0.0.1" --http.api "admin,debug,web3,eth,txpool,personal,ethash,miner,net" --cache 18000 --maxpeers 500 --datadir /someplace

getth attach 和 eth.syncing 给我看

{ currentBlock: 9606766, highestBlock: 9606883, knownStates: 345833179, pulledStates: 345782057, startingBlock: 9604320 }

所以我想我已经同步了。但是，当我运行 w3.eth.getBalance(some_address) 时，它返回 0。当我使用 Metamask 或 infura 时，我得到不同的值。

我也无法在以太坊（或任何其他代币）上与 Tether 交互：

ERC20_ABI = [..] tether_contract = w3.eth.contract('0xdAC17F958D2ee523a2206206994597C13D831ec7', abi=ERC20_ABI) tether_contract.functions.balanceOf(that_address).call()

结果：

Traceback (most recent call last):
      File "/usr/local/lib/python3.8/dist-packages/web3/contract.py", line 1513, in call_contract_function
        output_data = web3.codec.decode_abi(output_types, return_data)

        return decoder(stream)

        raw_data = self.read_data_from_stream(stream)
      File "/usr/local/lib/python3.8/dist-packages/eth_abi/decoding.py", line 305, in read_data_from_stream
        raise InsufficientDataBytes(
    eth_abi.exceptions.InsufficientDataBytes: Tried to read 32 bytes.  Only got 0 bytes
    
    The above exception was the direct cause of the following exception:
    
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/usr/local/lib/python3.8/dist-packages/web3/contract.py", line 957, in call
        return call_contract_function(
      File "/usr/local/lib/python3.8/dist-packages/web3/contract.py", line 1530, in call_contract_function
        raise BadFunctionCallOutput(msg) from e
    web3.exceptions.BadFunctionCallOutput: Could not transact with/call contract function, is contract deployed correctly and chain synced?

我做错了什么？

编辑：很长一段时间，它总是落后于网络约 64 个块。（即使使用 NVMe）

【解决方案1】：

{ currentBlock：9606766，highestBlock：9606883，knownStates：345833179，pullStates：345782057，startingBlock：9604320 }

所以我想我已经同步了

其实这意味着你的节点还在同步，eth_syncing结束后会返回一个空结果。

不同步时具有同步状态数据或 FALSE 的对象
