Smart Contract code:

    address Addr1

function myFunction(

How can I catch that event?

  • Are you sure that you've got the right contract (i.e., byte-code) deployed? – goodvibration Sep 12 at 14:29
  • Yes. If I deploy same contract in Remix, I can see event in the logs. Same contract I used for web3 but getting empt response. I'll check again. – Junior_K27 Sep 13 at 5:00
  • My bytecode was wrong. I need help with bytecode conversion. According to latest solc docs, we need to get evm.bytecode.object and then convert it into hexformat. Right? – Junior_K27 Sep 13 at 7:00
