TypeError: 'NoneType' object is not subscriptable

[datatalking]

In the code below I'm not sure how to resolve these issues.

1. This is a 'NoneType Error' which I've seen before but somewhere after digging intoyahoofinancials/yahoofinancials
   /data.py

I added the code in life 5 to test responses, but I've changed them all to 'none' in testing so, when I'm getting this error. Can you describe your process to debug this or is this depreciated code when PyCaret still references it...

2. How does my 16 items of commodities get cut down to twelve near line 10?
