Error: Incorrect padding

[algoarrayone]

Following is my code.

from dydx3 import Client
from web3 import Web3
from pprint import pprint
from datetime import datetime, timedelta
from dydx3.constants import API_HOST_SEPOLIA

ETHEREUM_ADDRESS = "0x31e221e887e8Df2e199fddd337B3a0dDff088D6d"
ETH_PRIVATE_KEY = "0x0000000000000000000000000000000000000000000000000000000"

STARK_PRIVATE_KEY = "05f02655252949ef04887d14fa28fd394461a100cee9ded5a9d31ff552930a9f"
DYDX_API_KEY = "4400776c-fc51-34af-93d7-747cdbb24627"
DYDX_API_SECRET = "1Xv-RYJyOO_PRnA0sC5WpxA5kwdGu9GmUyMhOUL"
DYDX_API_PASSPHRASE = "Ue9LuYqMxEAZ02OQmHp6"
HOST = API_HOST_SEPOLIA

HTTP_PROVIDER = "https://eth-sepolia.g.alchemy.com/v2/QW8oPlBILbZSf7ypLSt4r0bzwBwyKgTM"

client = Client(
    host=HOST,
    api_key_credentials={
        "key": DYDX_API_KEY,
        "secret": DYDX_API_SECRET,
        "passphrase": DYDX_API_PASSPHRASE,
    },
    stark_private_key=STARK_PRIVATE_KEY,
    eth_private_key=ETH_PRIVATE_KEY,
    default_ethereum_address=ETHEREUM_ADDRESS,
    web3=Web3(Web3.HTTPProvider(HTTP_PROVIDER))
)

print(client.private.get_account().data)

When I try to print get_account().data, the error generated as "Incorrect padding". What it means?
