Docker composer, constraint - did not find expected key

We using docker CE(latest) and docker composer version 3.I have a .yml for for 3 services but I want to constraint grafana to the master of the swarm. When adding the constraint I get

yaml: line 32: did not find expected key Tthe script is this:

version: '3'
services:
  influxdb:
    image: "influxdb:latest"
    volumes:
      - /mount/set/influxdb:/var/lib/influxdb
    ports:
      - "5076:5076"
    networks:
      - production

  kapacitor:
    image: "kapacitor:latest"
    environment:
      KAPACITOR_HOSTNAME: kapacitor
      KAPACITOR_INFLUXDB_0_URLS_0: http://influxdb:5086
    volumes:
      - /mount/set/kapacitor:/var/lib/kapacitor
    ports:
      - "9092:9092"
    networks:
      - production

  grafana:
    image: "grafana/grafana:latest"
      ports:
        - "7000:7000"
      networks:
        - production
      deploy:
        placement:
          constraints: [node.role == manager]
      volumes:
        - /iSCSIDisk/grafana/grafana.ini:/etc/grafana/grafana.ini
        - /iSCSIDisk/grafana/lib:/var/lib/grafana
      environment:
        GF_SECURITY_ADMIN_PASSWORD: secretsecret

      networks:
        production:
          external: true

I combed over the script several times and could not find any reason for the error, I may be overlooking something, I checked for non-spaces etc, and could not find anything, I checked other articles regarding the same error, and I don't seem to have any missing brackets or duplicates too. Your help will be much appreciated, thank you. :)

Your indentation is broken in the grafana section. Everything after image is spaced in two extra spaces.
