Getting "AttributeError: 'NoneType' object has no attribute 'string'"

[gbocsardi]

I run my code on python3 using the following:

$ .venv/bin/python -m congressionalrecord.cli 2001-01-06 2020-12-31 json
Traceback (most recent call last):

AttributeError: 'NoneType' object has no attribute 'string'

It looks similar to #33. If I manually adjust the start date to one day later, it continues on fine, until it encounters another one of the same error.
