Expected Behavior

It happened when I tried to get past events with name of event 'ProposalCreated'. Also it doesn't work with 'allEvents'. But it properly works for exapmle for events with name 'ProposalExecuted'.

Steps to Reproduce

import axios from 'axios';
// eslint-disable-next-line @typescript-eslint/no-var-requires,@typescript-eslint/naming-convention
const Contract = require('web3-eth-contract');

const getAbi = async (address: string, apiKey: string) => {
  const {data: response} = await axios.get(
    `https://api.etherscan.io/api?module=contract&action=getabi&address=${address}&apikey=${apiKey}`,
  );

  const isAbiValid = response && Number(response.status) === 1;
  if (!isAbiValid) {
    throw new Error('Failed to get abi!');
  }

  return JSON.parse(response.result);
};

const getPastEvents = async (address: string, event: string) => {
  const apiKey = ETHERSCAN_API_KEY;
  const infuraApiKey = INFURA_API_KEY;

  try {
    Contract.setProvider(`https://mainnet.infura.io/v3/${infuraApiKey}`);
    const abi = await getAbi(address, apiKey);
    const contract = new Contract(abi, address);
    const pastEvents = await contract.getPastEvents(event, {
      fromBlock: 0,
      toBlock: 'latest',
    });

    console.log(pastEvents);

    return pastEvents;
  } catch (err) {
    console.error(err);
  }
};

const test = async () => {
  const executedEvents = await getPastEvents('0xc4e172459f1e7939d522503b81afaac1014ce6f6', 'ProposalExecuted');
  console.log(executedEvents);
  const createdEvents = await getPastEvents('0xc4e172459f1e7939d522503b81afaac1014ce6f6', 'ProposalCreated');
  console.log(createdEvents);
};

await test();

Hello @Yurii-Pristay, This seems an issue related to having invalid UTF-8 data returned inside a string inside the events log. And we will investigate this further.

Yurii-Pristay commented 1 year ago

Hey, are there any new info on this?

@Yurii-Pristay could you narrow down block range where you are getting error?
