Issue with samba permissions

[killmasta93]

Hi Currently need to configure a docker samba for a printer which only has smbv1 to scan i was reading the read me but cant seem to get it working as the printer needs one user called scanner with full access and other user to only read that folder

so this is what i have so far but currently seem to be a permission issue this is my docker config

version: "3.5"
 
services:
  samba:
    image: crazymax/samba
    container_name: samba
    network_mode: host
    volumes:
      - "./data:/data"
      - "./scan:/scan"
    environment:
      - "TZ=Europe/Paris"
      - "SAMBA_LOG_LEVEL=0"
    restart: always 

and the config for the permissions

auth:
  - user: scanner
    group: scanner
    uid: 1000
    gid: 1000
    password: mypass
  - user: client
    group: client
    uid: 1100
    gid: 1200
    password: mypass

global:
  - "force user = scanner"
  - "force group = scanner"

share:
  - name: scannfiles
    path: /scan
    browsable: yes
    readonly: no
    guestok: no
    validusers: scanner,client
    writelist: scanner
    veto: no

but when the user scanner tries to login and create a folder it says denied not sure why

Thank you
