laravel "Undefined index: disabled when a Model is called

I am testing Laravel webform and having a problem when modifying the code. I have a customer list that shows all the added customers. I can create new customers, make them active or Inactive and submit. But now I am unable to navigate to the customer list page which is also an index page. Below is where I get error every time. I need help from you.

D:\wsPHP\blog\app\Customer.php

namespace App;

use Illuminate\Database\Eloquent\Model;
use App\company;
use App\Customer;

class Customer extends Model
{
    //Allow mass assignment
    //protected $fillable = ['name','email', 'mobile', 'active'] ;

    //Guarded
    protected $guarded =[];//Nothing is guarded when empty array, opposite of fillable

    protected $attribute =['$active'=>0,]; //default attribute

    public function getActiveAttribute($attribute){

        return [0=>'Inactive',1=>'Active',][$attribute];
    }
    public function scopeActive($query)
    {
        return $query->where('active',1);
    }
    public function scopeInactive($query)
    {
        return $query->where('active',0);
    }

    public function company()
    {
        return $this->belongsTo(company::class);
    }
}
