ERROR: Trying to get property of non-object

Hi I'm using talk-example and integrated parts of it into a fresh laravel 5.3 installation.

When I go to /message/1 for chatHistory between two users, I get the above ERROR. There are no conversations in the database.

MessageController.php
`<?php

namespace App\Http\Controllers;

use App\User;
use Illuminate\Http\Request;
use Nahid\Talk\Facades\Talk;
use Auth;

{
$this->middleware('auth');
Talk::setAuthUserId(Auth::user()->id);

    View::composer('partials.peoplelist', function($view) {
        $threads = Talk::threads();
        $view->with(compact('threads'));
    });
}

public function chatHistory($id)
{
    $conversations = Talk::getMessagesByUserId($id, 0, 5);
    $user = '';
    $messages = [];
    if(!$conversations) {
        $user = User::find($id);
    } else {
        $user = $conversations->withUser;
        $messages = $conversations->messages;
    }

    return view('messages.conversations', compact('messages', 'user'));
}

public function ajaxSendMessage(Request $request)
{
    if ($request->ajax()) {
        $rules = [
            'message-data'=>'required',
            '_id'=>'required'
        ];

        $this->validate($request, $rules);

        $body = $request->input('message-data');
        $userId = $request->input('_id');

        if ($message = Talk::sendMessageByUserId($userId, $body)) {
            $html = view('ajax.newMessageHtml', compact('message'))->render();
            return response()->json(['status'=>'success', 'html'=>$html], 200);
