Error while checking invoice

[rootgleb]

This code raises error:

from cryptobot import CryptoBotClient
from cryptobot.models import Asset
import config

client = CryptoBotClient(config.TEST_CRYPTOBOT_TOKEN, is_mainnet=False)
print(client.get_invoices(invoice_ids="814150"))

But it doesn't when invoice is not paid. Error:

Error:
TypeError: Invoice.__init__() got an unexpected keyword argument 'fee_in_usd'

I found out what the error was, to fix it you need to add this line:
fee_in_usd: Optional[str] = None
in models/init in class Invoice like this:

P.S. it is still error in library
