Describe the bug

AttributeError Traceback (most recent call last)
in

14 # loop through each report in the 'myreports' tag but avoid the last one as this will cause an error.
---> 15 for report in reports.find_all('report')[:-1]:
16
17 # let's create a dictionary to store all the different parts we need.

AttributeError: 'NoneType' object has no attribute 'find_all'
Expected behavior
Returns report dictionary
Side Note
Also generally, when I run the scraper in Jupyter Notebook it is very buggy, and I have to run the Grab the Filing XML Summary block multiple times. Do you think this could be due to the SEC throttling our requests?
