I am using laravel 5.8, and using laravel pusher "^4.1". Laravel pusher was working fine before 2 days ago. On, that day I had updated laravel composer and global laravel/installer to install new (another) laravel app. And, today when I am testing the old app the laravel pusher is not working. It is throwing following error:

My event file looks like:

class AmenityUploaded implements ShouldBroadcast {     use Dispatchable, InteractsWithSockets, SerializesModels;      public $property_id;      /**      * Create a new event instance.      *      * AmenityUploaded constructor.      * @param $property_id      */     public function __construct($property_id)     {         $this->property_id = $property_id;     }      /**  * Get the channels the event should broadcast on.  *  * @return \Illuminate\Broadcasting\Channel|array  */     public function broadcastOn()     { //        return new PrivateChannel('channel.amenity.'.$this->property_id);         return ['channel.amenity'];     }       public function broadcastAs()     {         return 'amenity-uploaded';     }      public function broadcastWith()     {         // This must always be an array. Since it will be parsed with json_encode()         $prop = Property::find($this->property_id);         $trash = "";         $warning = "";         if($prop->completed == 1){             $main = "<a href='".url('/admin/floor-stack/?company='.$prop->company_id.'&property='.$this->property_id)."' class='btn btn-xs btn-primary d-inline-block mr-1'>View</a>";             $trash = "<a href='#' class='btn btn-xs bg-light-grey delete_amenity mr-1'><i class='fa fa-trash text-white' aria-hidden='true'></i></a>";         }elseif($prop->completed == 2){             $main = "<a href='#' class='btn btn-xs btn-warning d-inline-block mr-1'>Pending</a>";         }elseif($prop->completed == 3){             $notice = Notice::where('property_id',$this->property_id)->where('file_type','1')->first();             $main = "<a href='".url('/admin/floor-stack/?company='.$prop->company_id.'&property='.$this->property_id)."' class='btn btn-xs btn-primary d-inline-block mr-1'>View</a>";             $trash = "<a href='#' class='btn btn-xs bg-light-grey delete_amenity'><i class='fa fa-trash text-white' aria-hidden='true'></i></a>";             $warning = "<a class='d-inline-block' href='".url('/admin/notice/'.$notice->slug)."' data-toggle='tooltip' data-html='true' title='The upload has some potential errors.

channel subsription

        var pusher = new Pusher("{{config('broadcasting.connections.pusher.key')}}", {             cluster: 'us3',             forceTLS: true         });          /** channel.amenity **/         let channelAmenity = pusher.subscribe(`channel.amenity`);         channelAmenity.bind('amenity-uploaded', function(data) {            // console.log(data);             $('#am_div_'+data.id).html(data.main+data.trash+' '+data.warning);         }); 

And, event is being fired from a laravel job as :

event(new AmenityUploaded($this->data['property_id'])); 

It just changed the status of a laravel job from running to completed.

If you need any further details, let me know.
