"Asset Transaction Not Supported" when trying to create a new ASA

[danmurphy1217]

Hello, I am trying to create a coin on top of the Algorand Blockchain. I generated two new accounts (creator and receiver) and am trying to create the Algorand Standard Asset by running the following code:

def create(passphrase:str= None):
    """
    creates the asset that is defined in `config.py`, signs it, and sends it
    to the algorand network if the senders passphrase is supplied. Otherwise,
    the transaction is written to a file.

    :param passphrase -> ``str``: the user passphrase.
    """
    transaction_data = add_network_params(client, asset_details)
    transaction = AssetConfigTxn(**transaction_data)

    if passphrase:
        transaction_info = sign_and_send(transaction, passphrase, client)
        print(f"Create asset confirmation, transaction ID: {transaction}")
        asset_id = transaction_info['txresults'].get('createdasset')
        print(f"Asset ID: {asset_id}")
    else:
        write_to_file([transaction], "create_coin.txn")

def sign_and_send(transaction: str, passphrase: str, client: algod.AlgodClient) -> Dict[str, str or int]:
    """
    sign and send a transaction to the algorand network. Return the transaction
    info when the transaction is completed.

    :param transaction -> ``AssetTransferTxn``: the transaction object.
    :param passphrase -> ``str``: the public key for the user involved in the transaction.
    :param client -> ``algod.AlgodClient``: an algorand client object.
    """
    private_key = mnemonic.to_private_key(passphrase)
    signed_transaction = transaction.sign(private_key)
    transaction_id = signed_transaction.transaction.get_txid()
    print("IN SIGN AND SEND")
    client.send_transaction(signed_transaction, headers={'content-type': 'application/x-binary'})
    transaction_info = wait_for_confirmation(client, transaction_id)
    return transaction_info

The error occurs during client.send_transaction(), and the full stack trace is this:

It seems like this is an issue between the two addresses (and their permissions/settings) and not within the code itself. I was following along with this tutorial and all of the coin-related code is publically available here. Let me know if there is any other information you need.

Hi @danmurphy1217, I don't see any issues with your code. The only reason you would get an error of asset transaction not supported would be if the network you are sending your asset creation transaction to does not support assets. Are you using a private network, and if so how did you create it?

[danmurphy1217]

@jasonpaulos I followed this tutorial pretty closely and wrote a script here that mirrors the tutorial.

The steps I took to run a node on MainNet were:

1. install the update.sh file, make it executable, and run it
2. cd into the node directory and run ./goal node start -d $ALGORAND_DATA
3. check the status of the node to make sure it is up and running

Then, for the TestNet I ran:

1. cd into the node directory
2. mkdir testnetdata
3. cp genesisfiles/testnet/genesis.json testnetdata
4. ./goal node start -d testnetdata

Is there any way to check if it is running on a private network? cat testnetdata/algod.net is 127.0.0.1:XXXX

[jasonpaulos]

@danmurphy1217 thanks for the info! When you get this issue are you connecting to your TestNet node? Could you let me know the output of goal node status for the node you're using?

[danmurphy1217]

Yes, I should be connecting to the TestNet node because I am using the testnetdata algod.token and algod.net values when I instantiate the algod.AlgodClient (line 99 in pos_etc/main.py).

The output of goal node status -d testnetdata is:

[jasonpaulos]

@danmurphy1217 thanks! I believe the issue is because your node has not caught up to the rest of TestNet yet. According to that status, your last committed block is 636047, but as of now TestNet is on block 13015459. Because your node is still working through past transactions, it's actually still using an old protocol version that doesn't support assets yet. You can see this by going to the consensus protocol link for your node and seeing it's still on the first commit for that repo.

Eventually your node will catch up to rest of the network and you should be able to use assets. However this may take a while, so you might want to use fast catch up to accelerate the process. If you do this, your node will get a recent snapshot of TestNet and it will only take a few seconds or minutes for it to collect the remaining blocks.

[jasonpaulos]

I'm going to close this because it's not specific to the Python SDK anymore, but feel free to continue responding here, or open another issue if there's a different problem related to this SDK.

[danmurphy1217]

thanks so much @jasonpaulos, that did the trick 🙌
