Describe the Problem
Hi, I'm trying to listen for events, I'm using ethers v6.12.1, node js 18.16.1. I've tried suggested fixes from issues raised earlier and even downgraded the package, I got another error. Please what could be the issue?
Code Snippet
const provider = new ethers.WebSocketProvider("wss://mainnet.infura.io/ws/v3/....");
const tokenContract = new ethers.Contract("0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe", [//abi],provider)
tokenContract.on('Transfer', (from, to, value) => {
console.log("transfer from===", from, "===to====", to, "===value===", value)
});
