I ended up finding issue #163 which pointed me in the right direction.

I had 16 rows in my activities table that were completely blank.

View:
select start_time from activities where start_time IS NULL;

Delete:
DELETE from activities WHERE start_time IS NULL;

I don't have a lot of experience with python so I may be way off base, but could you filter out null or empty datetimes in the get_years() method/function?
