When running a self-hosted version of n8n, you have to mount the n8n-task-runners.json file in the docker container and then either directly change "N8N_RUNNERS_STDLIB_ALLOW": "*" in the file or either add "N8N_RUNNERS_STDLIB_ALLOW" to the allowed-env array.

Here is an example docker-compose.yml file showing the implementation for the second option:

---
services:
  n8n:
    image: n8nio/n8n:1.121.1
    restart: always
    environment:
      - N8N_RUNNERS_ENABLED=true
      - N8N_RUNNERS_MODE=external
      - N8N_RUNNERS_BROKER_LISTEN_ADDRESS=0.0.0.0
      - N8N_NATIVE_PYTHON_RUNNER=true
    ports:
      - "5678:5678"
    volumes:
      - n8n_storage:/home/node/.n8n

  runner:
    image: n8nio/runners:1.121.1
    restart: always
    env_file: n8n.env
    environment:
      - N8N_RUNNERS_TASK_BROKER_URI=http://n8n:5679
      - N8N_RUNNERS_STDLIB_ALLOW=*
    volumes:
      - ./n8n-task-runners.json:/etc/n8n-task-runners.json
    depends_on:
      - n8n

volumes:
  n8n_storage:

And the n8n-task-runners.json file:
