This is my code: 

```
var docParent = "XXXXXXXXXXXXXXXXXXX";
var docsView = new google.picker.DocsView(google.picker.ViewId.FOLDERS);
        docsView.setParent(docParent);
var picker = new google.picker.PickerBuilder().
            addView(docsView).
            setOAuthToken(oauthToken).
            setDeveloperKey(developerKey).
            setCallback(pickerCallback).
            //setOrigin('http://localhost:61003').
            build();
        picker.setVisible(true);

```

I'd like to set a default folder that might have "sub-folders" and then pick a file inside of them. 
It was working fine but since a few months it just displays the folders but not the files inside them. So, I've tried to change the addView for a addViewGroup and add FOLDERS and DOCS but it doesn't work either. The folders works always fine, but when i select the sub-folder it says "No items on this folder".

Could you help me please? 

Thanks !
