Trying to get property 'conversation' of non-object

[shresthabiswas]

I have just tried to run your demo codes after everything has been installed into the domain server. The error encountered into my laravel 7 application. Let me show you where actually the issue occurred.
This is home.blade.php

@foreach($threads as $inbox)
                       @if($inbox->message->conversation->is_accepted) <!-- This is the line of code where error has been encountered -->
                           <a href="{{ route('chat' , [
                               'id' => $inbox->message->conversation->id
                           ]) }}">
                               <div class="about">
                                   <div class="name">{{$inbox->user->name}}</div>
                                   <div class="status">
                                       @if(auth()->user()->id == $inbox->message->sender->id)
                                           <span class="fa fa-reply"></span>
                                       @endif
                                       <span>{{ substr($inbox->message->text, 0, 20)}}</span>
                                   </div>
                               </div>
                           </a>
                       @else
                           <a href="#">
                               <div class="about">
                                   <div class="name">{{$inbox->user->name}}</div>
                                   <div class="status">
                                       @if(auth()->user()->id == $inbox->message->sender->id)
                                           <span class="fa fa-reply"></span>
                                       @endif
                                       <span>{{ substr($inbox->message->text, 0, 20)}}</span>
                                   </div>
                                   @if($inbox->message->conversation->second_user_id == auth()->user()->id)
                                       <div>
                                           <a href="{{ route('accept.message' , [
                               'id' => $inbox->message->conversation->id
                           ]) }}" class="btn btn-xs btn-success">Accept Message Request</a>
                                       </div>
                                   @endif
                               </div>
                           </a>
                       @endif

               @endforeach

This is HomeController.php index()

public function index()
   {
       $groups = Chat::getAllGroupConversations();
       $threads = Chat::getAllConversations();

       return view('home')->with([
           'threads' => $threads,
           'groups'  => $groups
       ]);
   }

When I dump and die into the $threads[0]->message, I find #relations null
