$newProperty->city = $request->input('city');

$newProperty->dic = $request->input('dic');

$newProperty->price = $request->input('price');

$img = $request->file('img_path');

$path = $img->store('images/resource/property/main/', ['disk' =>   'my_files']);

$newProperty->img = "public/".$path;

    foreach ($salse as $table_data){

        if($name == $table_data->p_name && $district == $table_data->district){

            dump($newProperty);

            $action = "error";

            echo('--------------');

            dd($table_data);

        }

    }

    if($action == "ok"){

        $newProperty->save();

        foreach ($request->file('more_img_path') as $imagefile) {

            $image = new Image;

            $path2 = $imagefile->store('images/resource/property/gallery/', ['disk' =>   'my_files']);

            $image->p_id = $property_id;

            $image->img = "public/".$path2;

            $image->save();

        }



            // **********************activity log************************

            $newLog = new Log();

            $uname;

            $user;

            foreach(session('login_user') as $id => $details){

                $uname = $details['name'];

I’m mention below error screenshot. There showing error “newProperty(save);” code line.
Can someone help me to fix this error? enter image description here
