Server port changes when accessing Image and File type fields

[intuji-vijayrana]

I am testing this plugin and working fine for all field types except Image and File. When I try to access those field, the port of laravel server changes.
I am trying to access as below:

$page = Corcel\Model\Page::find(2);
 return $page->acf->image_1;
OR
return $page->acf->custom_file;

The same works for others including the repeater. Anything I am doing wrong?
