Laravel Custom Exception is giving me Undefined property::$headers

I am working on an exception right now in laravel giving a weird behavior that I have not seen before and can't seem to find much information about. I am getting this error message Undefined property: App\Exceptions\UserNotApproved::$headers. Not sure whats going.

<?php

namespace App\Exceptions;

use Exception;

class UserNotApproved extends Exception
{
    /**
     * Report or log an exception.
     *
     * This is a great spot to send exceptions to Sentry, Bugsnag, etc.
     *
     * @param  \Exception  $exception
     * @return void
     */
    public function report(Exception $exception)
    {
        parent::report($exception);
    }

    /**
     * Render the exception into an HTTP response.
     *
     * @param  \Illuminate\Http\Request
     * @return \Illuminate\Http\Response
     */
    public function render($request)
    {
        return response()->view('errors.not_approved',['exception'=>$this],403);
    }
}
