Docker setup produces broken installation

[Nateowami]

I am attempting to follow the Docker quick start instructions at https://freetakteam.github.io/FreeTAKServer-User-Docs/Installation/mechanism/Docker/Quick_Start/

Based on my understanding of the instructions, I am running the following on Ubuntu 20.04:

git clone https://github.com/FreeTAKTeam/FreeTAKHub-Installation.git
cd FreeTAKHub-Installation/containers/
chmod -R 777 .
mv example-compose.yaml compose.yaml
docker compose up -d

And then navigating to localhost:500, I get the following error:

Traceback (most recent call last):
