When I run the script [`transfer_example_subaccount_transfer.py`](https://github.com/dydxprotocol/v4-clients/blob/main/v4-client-py-deprecated/examples/transfer_example_subaccount_transfer.py), I encounter an error, and the script does not work as expected.

Github link : [v4-clients/v4-client-py-deprecated/examples/transfer\_example\_subaccount\_transfer.py at main · dydxprotocol/v4-clients · GitHub](https://github.com/dydxprotocol/v4-clients/blob/main/v4-client-py-deprecated/examples/transfer_example_subaccount_transfer.py)

Additionally, when I integrate this code into my own project and execute it, I receive various errors in different places. What could be causing this issue, and how can I resolve it?

My output:

`python3 transfer_example_subaccount_transfer.py URL must start with one of the following prefixes: "grpc+https", "grpc+http", "rest+https", "rest+http" `

My code :

```auto
import asyncio
import logging
from v4_client_py.chain.aerial.wallet import LocalWallet
from v4_client_py.clients.dydx_subaccount import Subaccount

from v4_client_py.clients.dydx_validator_client import ValidatorClient
from v4_client_py.clients.constants import BECH32_PREFIX, Network

DYDX_TEST_MNEMONIC = (
    ""
)

async def main() -> None:
    network = Network.config_network()
    client = ValidatorClient(network.validator_config)
    wallet = LocalWallet.from_mnemonic(DYDX_TEST_MNEMONIC, BECH32_PREFIX)
    subaccount = Subaccount(wallet, 0)
    try:
        tx = client.post.transfer(
            subaccount=subaccount,
            recipient_address=subaccount.address,
            recipient_subaccount_number=1,
            asset_id=0,
            amount=5_000_000,
        )
        print(" **Transfer Tx**")
        print(tx)
    except Exception as e:
        print(e)

if __name__ == " __main__":
    logging.basicConfig(level=logging.INFO)
    asyncio.run(main())

```
