IB historical data error

i had a function to read historical data from Interactive Brokers, and was working good.

now i'm trying to run again (after some month) and stopped working returing this errors:

'Warning: You submitted request with date-time attributes without explicit time zone. Please switch to use yyyymmdd-hh:mm:ss in UTC or use instrument time zone, like US/Eastern. Implied time zone functionality will be removed in the next API release'

Error: 'No historical data query found for ticker id:1418'

the CODE:

ib = ibtws('127.0.0.1', 7497,1)

ibContract = ib.Handle.createContract;

ibContract.symbol = 'MSFT'; %'MSFT';

ibContract.secType = 'STK';

ibContract.exchange = 'SMART';

ibContract.primaryExchange = 'NASDAQ';

ibContract.currency = 'USD';

startdate = datenum(2023,03,16,12,30,00);

enddate = datenum(2023,03,17,13,30,00);

barsize = '10 secs'; %5 secs 10 secs 1 min

ticktype = 'ask'; %bid or ask

tradehours = true; % false(default) ; true

ask = timeseries(ib,ibContract,startdate,enddate,barsize,ticktype,tradehours);
