Operations graph not populating and 500 error from operations summary endpoint

[timbrigham-oc]

Describe the bug
The graph svg isn't populating correctly on any operations, including both currently running and historical instances.

Viewing the dev tools in chrome, I'm seeing a 500 error from the following endpoint:
https://.cloudapp.azure.com/api/v2/operations/summary

With a response of 500 Internal Server Error Server got itself in trouble.

Nothing in the SSH console shows any errors from Caldera that look related.

I do see a distutils warning when I start with my Python 3.12.3 venv.

To Reproduce
Steps to reproduce the behavior:
Visit the operations page

Expected behavior
Graph SVG should load.

Make sure that previous operations containing Dead Agents are stopped. Previous running operations that contain dead agents prevent additional queries to be ran, which stops the population of Graph SVGs for newer operations. Graph SVGs only appear for agents that are alive where their operations are still running.

Things to try:

1. Stopping Operations with dead agents.
2. Removing all previous operations and start a new operation with alive agent.
