**BUG** blueprint file upload no longer working correctly, creates folder at root of GRAV

[MattAppleton]

I ran across this recently with a site with custom blueprint that has a file upload for a video background like so...

here's my 'default.yaml

extends@: default

form:
  fields:
    tabs:
      fields:
        content:
            type: tab
            fields:
              header.backgroundvideoupload:
                name: backgroundvideo
                type: file
                label: Background video upload
                multiple: false
                destination: '@self/videos'
                accept:
                  - video/*

              header.backgroundvideo:
                type: filepicker
                folder: '@self/videos'
                label: Select a background video
                preview_images: true

this USED to work fine, saving a file into the relevant page folder in a subfolder 'videos'

But now it creates a folder called '@self' with a subfolder 'videos' at the root level of the Grav install folder.

Just tested this on a completely vanilla fresh install of Grav 1.7.7 admin 1.10.6

I am trying to make a simple blueprint that uploads background images / videos into either a specific page or ideally a subfolder per page.

Seems Grav doesn't resolve blueprint folder .yaml such as

folder: 'page:/backs'

folder: 'self@/backs'

etc...

@mahagr Thanks for looking... so I can resolve with that repo update?

@MattAppleton I'm working on the second part of the fix based on the blueprints you gave to me, but I need a bit more time to get it right.

Also needs a fix in trilbymedia/grav-plugin-flex-objects@e4f2e29

@w00fz There is still a bug in displaying above file field. It gets the files from the main media object, not from the media object from that input. I have fixed the field so it mostly works, but it cannot be fully fixed before the right settings are being used.

AJAX call is not sending name in POST containing the field name, in above case header.backgroundvideoupload.

Basically you need to change themes/grav/app/pages/page/media.js line 76+ fetchMedia() method to work just like add/delete.

This works fine for me, seems resolved.
There is no point in sending the name for that location you specified @mahagr, that's pagemedia and uses its own listmedia task, it's always just pagemedia.

the header.backgroundvideoupload field is of type file, which uses the task getFilesInFolder and that is already properly sending the necessary information needed:
