Hey!

Unless you run the container as the root user, you won’t have access to write in /home/node/.n8n. It’s not really recommended, as if an attacker takes control they will have sudo access. Here’s how:

docker volume create n8n_data

docker run -u 0 -it --rm \
 --name n8n \
 -p 5678:5678 \
 -e GENERIC_TIMEZONE="<YOUR_TIMEZONE>" \
 -e TZ="<YOUR_TIMEZONE>" \
 -e N8N_ENFORCE_SETTINGS_FILE_PERMISSIONS=true \
 -e N8N_RUNNERS_ENABLED=true \
 -v n8n_data:/root/.n8n \
 docker.n8n.io/n8nio/n8n

*Notice the -u 0 (root user) and -v n8n_data:/root/.n8n (moving .n8n under root, so the root user has access)

Recommended way would be to create a docker compose file. Inside create a second volume to which you will have write access:

volumes:
      - /n8n-data:/home/node/.n8n # you can't write here
      - ./n8n-output:/data  # you can write here

Let me know if this help and feel free to mark as solution if it did

Thanks, I included the second line in volumes. It worked perfectly. And I got the written json file in the n8n-output folder.
