@danguyf thanks for working on this! When I run this locally using your branch (without adding any data manually), I get the following error:

./manage.py get_overview

As you said, I was able to reproduce this by restarting my docker to load the default data and then not loading test data.

I have added error handling to handle cases where there are no committees, no reports, and/or no contacts.

This seems great. Really like how you used quantiles to solve this problem. Perfect tool for the job. Sometimes forget python has all those features built-in
