Invalid argument supplied for foreach() in angular_media_field_widget_form_validate()

Hi,

Just wanted to give a try to this module, understanding that it is in MVP state.

Indeed, I'm getting the following error:

Warning: Invalid argument supplied for foreach() in angular_media_field_widget_form_validate() (line 172 of ../modules/angular_media/includes/angular_media.field.inc).

If anybody can help me to go one step further, it would be appreciate.

Thanks.
