ibflex.parser.FlexParserError: CashReportCurrency has no attribute 'endingCashIBUKL'

[Dr-Nuke]

Since very recently, my flexqueries do not parse anymore. one month ago, it still worked fine. Python 3.7.10 ibflex 0.15 (same with 0.14) WSL Ubuntu 18.04.4 LTS

sample code:

import yaml
credsfile="../ibkr.yaml"
with open(credsfile, 'r') as f:
                config = yaml.safe_load(f)
                token = config['token']
                queryId = config['queryId']

from ibflex import client, parser, Types
response = client.download(token, queryId)

print('received valid FlexQuery information:\n' + str(response[:270]))
print('failing parsing of the response:')
parser.parse(response)

received valid FlexQuery information:
b'<FlexQueryResponse queryName="my monthly flexquery" type="AF">\n<FlexStatements count="1">\n<FlexStatement accountId="U*******" fromDate="2022-06-01" toDate="2022-06-30" period="LastMonth" whenGenerated="2022-07-02;10:12:05">\n<CashReport>\n<CashReportCurrency currency="BASE_S'...
failing parsing of the response:

FlexParserError: CashReportCurrency has no attribute 'endingCashIBUKL'

So add the endingCashIBUKL? IB does this stuff all the time, that's why I made it so easy to work with ibflex.Types. CashReportCurrency is on line 502, and you appear to be holding valid data in your hands. Let me know if you can't figure it out
