Request model error xrpl.models.requests.ledger_entry.Directory

[mDuo13]

This model requires a dir_root field, but that field should be optional.

Steps to Reproduce

The following code throws an error:

from xrpl.models.requests import LedgerEntry
from xrpl.models.requests.ledger_entry import Directory

directory_request = LedgerEntry(
    directory=Directory(
        owner="rPT1Sjq2YGrBMTttX4GZHjKu9dyfzbpAYe",
        sub_index=0
    ),
    ledger_index="validated"
)

The error is:

xrpl.models.exceptions.XRPLModelException: {'dir_root': 'dir_root is not set'}

Workaround / Expected Result

The following code runs successfully, including making a successful query to Testnet:

from xrpl.clients import JsonRpcClient
from xrpl.models.requests import LedgerEntry

directory_request = LedgerEntry(
    directory={
        "owner": "rPT1Sjq2YGrBMTttX4GZHjKu9dyfzbpAYe",
        "sub_index": 0
    },
    ledger_index="validated"
)

client = JsonRpcClient("https://s.altnet.rippletest.net:51234/")
response = client.request(directory_request)
print(response.result)
