myContract.getPastEvents returns undefined event

Question

I am using Web3 1.3.0. Connecting using Node. Also if I try to enter the name of my Event I get an error saying that event does not exist. This is what I get, shouldn't event have a value ?

I am using Infura.

var web3 = new Web3("wss://rinkeby.infura.io/ws/v3/xxxxxxxxxxx

myContract.getPastEvents('allEvents',{fromBlock:1},function(err,results){
  console.log("err:",err);
  console.log("res:",results);
});

Answer 1

I believe this is a common problem. It happens when the ABI you're using doesn't match the event being taken, thus resulting in missing information. I run into that issue and that was my solution.

Hope it helps some folk out there :)

Answer 2

Well, I could not figure this out. So scrapped it and switched to https://docs.ethers.io/v5/ and life is much better, ethers returns the logs and exposed the events I can extract the data I need. I really would have liked to figure out the solution to continue to use Web3js v.1.x but I could not find answers or support.

Answer 3

I got the same issue. It turned out that I forgot to update the ABI file after I added the event to the smart contract.

Hopefully this helps.
