I'm using Filepond in my project and its successfully working in upload and save case.

But in a scenario, where I've to retrieve all elements including uploaded files on separate page.

So, in that scenario, I send an json:

'source' => 1,
        'options' => [
            'type' => 'local',
            'file' => [
                'name' => 'abc',
                'size' => 100,
                'type' => 'image/...',
            ],
            'metadata' => [
                'poster' => 'file_path',
            ],
        ],

to ajax response and uploaded files are shown in filepond element, but while submitting the form (pre-populated files) Filepond automatically trigger the revert method and delete the uploaded files.
