("network next_default not found")
Error updating pod status Pod matching query does not exist.
```

Start by reproducing the deployment failure and read deploy in app.py around line 448, where docker.containers.run is called. Inspect how the Docker network named next_default is expected to be created or selected. Done means the container starts without the network-not-found error and pod status updates successfully.
