Token transaction do not return any event

[FrancescoGrazioso]

Using React, i'm trying to execute a token transfert using Hedera Token Service.
When i send the transaction to HashConnect the wallet prompts me to approve the transaction, but after that nothing happens.
Here's my code:

`export async function buyRTTToken(token, trsuaryAccountId,reciverAccountId) {
const client = hederaClient();
let transaction : TransferTransaction = await new TransferTransaction();
transaction.addTokenTransfer(token.tokenId, trsuaryAccountId, -10);
transaction.addTokenTransfer(token.tokenId, reciverAccountId, 10);
transaction.freezeWith(client);

await sendTransaction(transaction, reciverAccountId);

}`

`export async function sendTransaction(tx: Transaction, signignAccount: string) {
let transactionBytes: Uint8Array = tx.toBytes();

const transaction: MessageTypes.Transaction = {
    topic: saveData.topic,
    byteArray: transactionBytes,
    metadata: {
        accountToSign: signignAccount,
        returnTransaction: false
    }
}

await hashconnect.sendTransaction(saveData.topic, transaction)

hashconnect.transactionResponseEvent.once((data) => {
    console.log("transaction response", data)
})

}`

The following code aims to let the reciving user to sign the transaction and to pay for the fees of tranfer, since he is requesting token from the tresuary account

@FrancescoGrazioso Could you provide a screenshot of the console after clicking "Approve" in the demo wallet? It should display "SUCCESS" after a few moments, or throw an error if execution failed.

[teacoat]

Or - this could be happening because the token you are trying to transfer is not associated to the demo account

[FrancescoGrazioso]

The transaction to associate the token to the wallet account has the same problem, i'll attach the console on the approving transaction.
The problem is the same, i got no response from the event handler and the console/wallet do not display any "SUCCESS" message.

The following is the code that i'm using to approve the transaction

`
export async function associateTokenWithAccount(token, accountId) {
const client = hederaClient();
let transaction = await new TokenAssociateTransaction();
transaction.setAccountId(accountId);
transaction.setTokenIds([token.tokenId]);
transaction.freezeWith(client);

await sendTransaction(transaction, accountId);

}
`

`
export async function sendTransaction(tx: Transaction, signignAccount: string) {
let transactionBytes: Uint8Array = tx.toBytes();

const transaction: MessageTypes.Transaction = {
    topic: saveData.topic,
    byteArray: transactionBytes,
    metadata: {
        accountToSign: signignAccount,
        returnTransaction: false
    }
}

await hashconnect.sendTransaction(saveData.topic, transaction)

hashconnect.transactionResponseEvent.once((data) => {
    console.log("transaction response", data)
})

}

`

Yes so the demo wallet doesn't support the token associate function yet - it's still very much a WIP but I will prioritze adding token association.

Your events are going through fine, the wallet just doesn't have the UI to handle it yet!

[FrancescoGrazioso]

Ok thanks, i'll close the issue when you'll release the new version of the wallet

[teacoat]

Sounds good - I'll tag you when its ready :)

[teacoat]

@FrancescoGrazioso I've updated the demo wallet to support token associate/disassociate

[teacoat]

Keep an eye on the console when using it - errors such as "TOKEN_ALREADY_ASSOCIATED" aren't handled by the demo wallet yet

[FrancescoGrazioso]

Still nothing from the console, on every transaction i try.
I tried:

• token association
• token dissociation
• token transfert

I'll attach some screen

Hmmm that looks to me like it should work - can you reach out to me (pluto) on discord?

[teacoat]

There was a bug in the demo where errors werent returning correctly - if you try now both the success and error transaction response events should fire - here is the log from the demo dapp, you can see both transaction responses there!

[FrancescoGrazioso]

It is giving me now the following error

I reached you on discord

[FrancescoGrazioso]

The problem was in the way i was freezing the transaction, with the new code it works!
