[web3/web3.js]getPastLogs 缺少日志

import Web3 from 'web3'; // 4.1.2

const url = ''; // your rpc url
const web3 = new Web3(url);
const syncEvent = web3.utils.sha3('Sync(uint112,uint112)');

async function getSync({ transactionHash, chain, logIndex, address, blockNumber }) {
    try {
        const logs = await web3.eth.getPastLogs({
            fromBlock: blockNumber,
            toBlock: blockNumber,
            address: address, // even without this parameter it fails
            topics: [
                [syncEvent]
            ]
        });
        // find the specific syncEvent = swapEvent logIndex  -1
        const sync = logs.find(d => d.address.toLowerCase() === address.toLowerCase() && parseInt(d.logIndex) === (logIndex--)); 
        const decoded = web3.eth.abi.decodeParameters(['uint112','uint112'], sync.data);
        return { reserve0: decoded[0], reserve1: decoded[1] };
    } catch (err){
        console.log(err)
    };
}

const sync = await getSync({ 
    transactionHash: '0xa4a2709219742f4152888a6e9bf64fa225d32cf4a48b00be0c288b0cbb277f31', 
    chain: 'ETH', 
    logIndex: 215, 
    address: '0xef9ef6e07602e1e0419a5788f1d85e0698eab077', 
    blockNumber: 18484534 
});

console.log(sync)

const receipt = await web3.eth.getTransactionReceipt('0xa4a2709219742f4152888a6e9bf64fa225d32cf4a48b00be0c288b0cbb277f31');
console.log(receipt)

上面的代码将无法从 getPastLogs 获取同步事件，但是收据中会显示我们要查找的特定日志确实存在于收据中。

我认为如果日志存在于收据中，它应该显示在 getPastLogs 中。

我尝试重现该问题，但似乎效果很好：以下是示例：

我已经创建了一个包含类型为 uint112 的事件的合约

So, everything works correctly. 
I think the problem in your code is this condition `parseInt(d.logIndex) === (logIndex--)`
Could you please debug and check what is the value of `const logs = await web3.eth.getPastLogs(...)` in your code?

我的第一篇文章包含应该重现问题的示例代码。

logIndex--只是为了从 uniswap v2 池上的交换事件中查找同步事件。

Sv3nskie

在你的情况下，它是不正确的 blockNumber。

您的交易哈希值https://etherscan.io/tx/0xa4a2709219742f4152888a6e9bf64fa225d32cf4a48b00be0c288b0cbb277f31是 blockNumber = 18484533n

如果你只设置这个块号 - 一切都会正常

我还删除了这段代码parseInt(d.logIndex) === (logIndex--)

async function getSync({ logIndex, address, blockNumber }) {
        try {
            const logs: Array<any> = await web3.eth.getPastLogs({
                fromBlock: blockNumber,
                toBlock: blockNumber,
                address: address, // even without this parameter it fails
                // @ts-ignore
                topics: [syncEvent],
            });

            const sync = logs.find(d => d.address.toLowerCase() === address.toLowerCase());
            console.log('sync',sync)
            // sync {
