how to decode action from transaction?

[dev-dantealighieri]

hi, I'm trying to decode Action from SignedTransaction object, I can decode memo and quantity, but unable to decode from and to into string objects.

here's what I do.

const transaction = Transaction.from(signedTransaction);
const action = Action.from(transaction.actions[0]);

const abi = await contractKit.load('eosin.token');
const decodedAction = action.decodeData(abi.abi) as any;

// from is Uint64, but I need address of account, e.g `garlicbutter`
const from = decodedAction?.from?.value; // ❌
const to = decodedAction?.to?.value.toString(); // ❌
const amount = decodedAction?.quantity?.value; // ✅
const memo = decodedAction?.memo;  // ✅

Can you provide what the value of signedTransaction is so we can reproduce this?

Actually, maybe this helps:

const data = {
    account: 'eosio.token',
    authorization: [
        {
            actor: 'from',
            permission: 'active',
        },
    ],
    data: {
        from: 'foo',
        memo: '7783298',
        quantity: '1.0000 EOS',
        to: 'bar',
    },
    name: 'transfer',
}

const contract = await mockKit.load('eosio.token')
const action = Action.from(data, contract.abi)
const decodedAction = action.decodeData(contract.abi) as any

console.log(decodedAction)
console.log(String(decodedAction.from))
console.log(String(decodedAction.to))

That renders out both the from and to fields as strings. If you don't cast it to a string, it'll be a Name type value.
