Agent-Zero crashes during memory initialization (monologue_start → Memory.initialize) when running via Docker

[Abin-Sec]

Hi Team,

I am facing an issue while running agent0ai/agent-zero:latest via Docker. The agent crashes before executing any command, during the memory initialization phase.

The error occurs even when running a simple command like:

Error:

Steps I followed to download the Docker image and run the Docker container:

docker pull agent0ai/agent-zero
docker run -p 50001:80 agent0ai/agent-zero

Debugging Performed

Inside the container:

✔ Running as root

whoami → root
uid=0(root) gid=0(root)

✔ /a0 is writable

touch /a0/testfile  → success

✔ SQLite is available

python3 -c "import sqlite3"

✔ Clean restart performed

• Container removed and recreated
• No custom mounts
• Fresh image pull

❌ Issue still persists

The crash happens immediately during memory bootstrap and retries in a loop.

I have added the API keys as shown below:
