Admin Image upload blueprint

Hi

I’m actually build a site with some modules in modules (Home > Module > Submodule).
For one of these submodules I created an blueprint with Image upload:

 title: Boxes
@extends: default

form:
  fields:
    tabs:
      fields:
        box:
          type: tab
          title: Box
          fields:
            header.box:
              name: box
              type: list
              label: Box
              fields:
                .title:
                  type: text
                  label: Title
                .text:
                  type: editor
                  label: Content
                .picture:
                  type: file
                  label: Picture
                  destination: '@self'
                  accept:
                    - image/*

This blueprintlayout normally works fine, but in the submodules the image upload doesn’t work properly. It upload the image in the submodule, but it does not generate the correct frontmatter in the submodule, just an empty
picture: { }
entry.

I use Grav v1.7.0-rc.10

Maybe someone has an idea :slight_smile:

Thanks for help.
