Laravel using View Composer in my routes with htmlspecial error

I was trying to do a query in my routes for the view composer to load all the records and count it and display it in my sidebar for purposes.

I think there is no problem with the query since it worked in my shell using the php artisan tinker for testing purposes of the query.

But I got this error when I try to do it in my routes and pass it to the menu.blade.php

Here is the code in my routes with the view composer function.

// Menu View for Microbiologist
View::composer('microbiologist-dashboard.layouts.menu', function($view)
{
    $view->with('counts', [
        'microbiologist_task' => App\Models\AnalysisRequest::where('status', 'under_analyzation')
        ->whereHas('actors', function ($query) {
            $microbiologist = Auth::guard('microbiologist')->user()->id;
            $query->where('microbiologist_id', $microbiologist)->count();
        })
    ]);
});

and here is the code in my menu.blade.php

<span class="pull-right-container">
            @if($counts['microbiologist_task'])    
                <small class="label pull-right bg-yellow"></small>
            @else
            @endif
        </span>

Here is the screenshot of the error.

is there something wrong with the config of my project about UTF-8? or should I use some helpers. Thanks btw I am using Laravel 5.5

Appreciate if someone could help. Thanks in advance.
