Description

Hello, it seems Dockge doesn't support number / integer declarations for group_add in the compose file.

group_add:
  - 999

This results in complete inability to use / see the entire stack.

Please see below for more info.

👟 Reproduction steps

Here is an example compose to reproduce:

services:
  dozzle:
    container_name: dozzle
    image: amir20/dozzle
    user: 802:802
    group_add:
      - 999
    restart: unless-stopped
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
    ports:
      - 127.0.0.1:8080:8080

👀 Expected behavior

This should work and not break Dockge :)

😓 Actual Behavior

In Terminal, an error can be seen:

1 error(s) decoding:

* 'group_add[0]' expected type 'string', got unconvertible type 'int', value: '999'

Containers have N/A state, Bash for container doesn't work, etc.
