Rebuild NVIDIAs Multi-Agent Chatbot Demo

The Multi-Agent Chatbot Demo fails to upload documents from the sidebar.
I have alread tried to rebuild the frontend and all other containers without success.
How can I start from scratch? I want to remove everything related to this demo only but I struggle to clone just this one playbook from github and keep the other stuff untouched.
I’ve looked for instructions but had no luck so far.

After some research I did use this commands to only download this playbook and start from scratch:

#Bash
cd dgx-spark-playbooks

rm -rf nvidia/multi-agent-chatbot

git checkout origin/main – nvidia/multi-agent-chatbot

After the files have been downloaded, you can proceed completing setting up the demo:

cd dgx-spark-playbooks/nvidia/multi-agent-chatbot/assets
chmod +x model_download.sh
./model_download.sh
docker compose -f docker-compose.yml -f docker-compose-models.yml up -d --build
