I am using

const decodedEvent = Abi.decodeEvent(Uint8Array.from(Buffer.from("00000064a7b3b6e00d000000000000000000000000000000000000000000000000", 'hex'))) 
(00000064a7b3b6e00d000000000000000000000000000000000000000000000000 is the data in the contracts::contractemitted event.)

But I cannot access the actual argument values, only their types. I'd like to be able to access the values when decoding the event. What am I missing?

Here's the decodedEvent.event.args enter image description here

Currently when accessing the decodedEvent.event.args, I only see the names and types. Where can I access the values?

  • Did you check the content of decodedEvent.event.data?

IIRC the values should be in decodedEvent.args.

  • it isn't there, could it be due to an incorrect abi?

  • Might be the case, but I'm not sure. Commented Sep 8, 2022 at 9:30

I use this:

if (result.status.isInBlock) {

  result.events.forEach(({event, phase, topics}) => {

    if (api.events.contracts.ContractEmitted.is(event)) {

      const [account_id, contract_event] = event.data

      let decoded = new Abi(metadata).decodeEvent(contract_event)
      decoded = JSON.parse(JSON.stringify(decoded));
