I created a geth Ethereum private chain and successfully committed the transaction through web3.js and saw the corresponding transaction in the specified block, but my web3.eth.getPastLogs() method always returns an empty array.

I query the specified log with the following code, get an empty array.

var options = {
  fromBlock: 0,
  toBlock: 164
};
const logs = await web3.eth.getPastLogs(options);
console.log(logs);

But there is actually a transaction on this block:

> web3.eth.getBlockByNumber(164)

Here is the version of my geth and the startup command information:

Version: 1.10.12-stable

geth --datadir data/folder --networkid 1541 --http --http.api "eth,net,web3" --http.addr "0.0.0.0" --http.port "8545" --http.corsdomain "*" --syncmode full --nodiscover console

I've been looking for a long time but I can't find the problem. Can anyone help me...

I tried this command on the goerli test net as expected.

    It's possible that your geth node is not indexing the logs. By default, geth nodes are configured to only index a certain range of blocks for events and logs. You can try increasing the --gcmode flag when starting geth to index more blocks. For example, you can try using --gcmode archive to index all blocks. – marsh-wiggle Apr 12 '23 at 10:07
  • Thank you for your suggestion. I tried to add this flag, but unfortunately the above problem still exists. @marsh-wiggle – ATFWUS Apr 12 '23 at 10:29
