Bug report: query_account not working

[furester]

Prerequisites

• I am running the latest CosmPy version.
• I checked the documentation and found no answer to my problem.
• I checked the existing issues to make sure my problem has not already been reported.
• I have read the code of conduct before creating this issue.

Expected Behavior

I expect to receive an Account object filled with all information, in order to use it in Transaction.seal and Transaction.sign

Current Behavior

getting this error:

Traceback (most recent call last):
  File "/app/queryaccount_test.py", line 66, in <module>
    main()
  File "/app/queryaccount_test.py", line 62, in main
    account = ledger_client.query_account(wallet.address())
  File "/usr/local/lib/python3.10/site-packages/cosmpy/aerial/client/__init__.py", line 264, in query_account
    raise RuntimeError("Unexpected account type returned from query")
RuntimeError: Unexpected account type returned from query

To Reproduce

i'm using this code:

from bip_utils import Bip39SeedGenerator, Bip44, Bip44Coins

from cosmpy.aerial.client import LedgerClient, Validator
from cosmpy.aerial.config import NetworkConfig
from cosmpy.aerial.wallet import LocalWallet
from cosmpy.crypto.keypairs import PrivateKey

def main():
    """Run main."""
    
    mnemonic = "<SEED PHRASE>"

    cfg = NetworkConfig(
        chain_id="mantle-1",
        url="grpc+https://grpc.assetmantle.nodestake.top",
        fee_minimum_gas_price=0,
        fee_denomination="umntl",
        staking_denomination="umntl",
    )
    ledger_client = LedgerClient(cfg)

    #ledger_client.gas_strategy()

    seed_bytes = Bip39SeedGenerator(mnemonic).Generate()
    bip44_def_ctx = Bip44.FromSeed(seed_bytes, Bip44Coins.COSMOS).DeriveDefaultPath()

    wallet = LocalWallet(PrivateKey(bip44_def_ctx.PrivateKey().Raw().ToBytes()), prefix="mantle")
    account = ledger_client.query_account(wallet.address())


if __name__ == "__main__":
    main()

to reproduce you need to fill mnemonic with your seed phrase

Context

running in docker, python:3.10-slim as base image with python3-dev package added
