Laravel htmlspecialchars() expects parameter 1 to be string, object given

Question

I am trying to send the data from a Contact form to email, but I am getting the following error htmlspecialchars() expects parameter 1 to be string, object given. Given below is my code. This is from a blog I found trying to get this done. I followed all the steps mentioned there.

ContactController.php

 public function index() {
        return view('front.contact');
    }

    public function storeForm(Request $request) {
        $this->validate($request, [
           'name' => 'required',
           'email' => 'required|email',
           'phone' => 'required|regex:/^([0-9\s\-\+\(\)]*)$/|min:10',
           'message' => 'required'
        ]);

        contact::create($request->all());

        \Mail::send('email', array(
            'name'=> $request->get('name'),
            'phone'=> $request->get('phone'),
            'email'=> $request->get('email'),
            'message'=> $request->get('message')
        ), function ($message) use ($request) {
            $message->from($request->email);
            $message->to('olindo.testing@gmail.com')->subject('Hello Admin | New Appointment');
        });

        return back()->with('success', 'Thank you for contacting us. We will get back to you soon.');
