Laravel database images update failue

I am trying to update images in my database.I am using laravel 5.4 version. I am getting this error.

Type error: Argument 1 passed to Illuminate\Database\Eloquent\Builder::make() must be of the type array, object given, called in C:\xampp\htdocs\laravel_eshopper\vendor\laravel\framework\src\Illuminate\Database\Eloquent\Model.php on line 1357
