Description:

Action with Trix field which enabled file upload does not upload files correctly.

Action is appended to User resource:

<?php

namespace App\Nova\Actions;

use Laravel\Nova\Actions\Action;
use Laravel\Nova\Fields\Trix;
use Laravel\Nova\Http\Requests\NovaRequest;

class TestAction extends Action
{
    public function fields(NovaRequest $request)
    {
        return [
            Trix::make('Reason')->withFiles('public')
        ];
    }
}

After pasting image to Trix field in Nova, there is 404 error:

Failed to load resource: the server responded with a status of 404 (Not Found): http://127.0.0.1:8000/nova-api/users/field-attachment/reason

Uploading when Trix field is added to Resource works correctly.

Detailed steps to reproduce the issue on a fresh Nova installation:

1. Create Action
2. Append it to any Resource
3. Add Trix field to Action and enable upload by withFiles() method
4. Try to paste image to Trix field on Nova UI
