Card-mod issues

Hello to all,

Can anyone help or guide me how to get this work with custom: card-mod. It was working with card-modder.

  type: entities
  show_header_toggle: 'off'
  entities:
      - type: section
        label: MAIN BUILDING
     - type: 'custom:vertical-stack-in-card'
       cards:
           - type: horizontal-stack
             cards:
                 - type:  custom:card-modder
                   card:
                      type: picture
                     image: /local/background.jpg
             style:
                border-radius: 2px

Indentation is incorrect for the image here:

                   card:
                      type: picture
                     image: /local/background.jpg
