Ticker seems to be bugged on certain types of input #336
Description
Intermittently putting in an array from df.index.levels[0].to_list() causes a problem on the historical prices.
Have a dataframe with the symbols as an index (I have multiindexed to 0: symbol and 1: datetime)
gets = df.index.levels[0].to_list()
gets[0]
'A'
trial = Ticker(gets, asynchronous=True)
data = trial.history(period='4d', interval='1m')
Traceback (most recent call last):
File "", line 1, in
File "/home/sanjurjo/backtesting/.yfin/lib/python3.12/site-packages/yahooquery/ticker.py", line 1285, in history

** Expectation
Should return the data, it does most of the time, but sometimes it just misses, like this

Additional context
I saw that there was another mention of this, but I am experiencing it intermittently, so I'm not sure what the problem is, actually, other than something funky with the build of the array that's being put into the Ticker command.
