I'm running comfyui in docker, so I often rebuild from scratch. By doing that, I'd loose the database. Solution would be to place the database somewhere under /data/custom_nodes/ComfyUI_PromptManager, because /data would be persisted as per the docker configuration. However, the change that is advised has no effect. The database sits in (local to the container) /app/ComfyUI and gets deleted when container is rebuilt.
