Data record in the Database in Laravel 5.4?

I've got a project in progress but I still do not know Laravel very well, and I'm trying to save the data in the database using this code in controller :

public function store(Request $request)
{
    $validator = \Validator::make($request->all(), [
        'name' => 'required',
        'description' => 'required',
        'coverage' => 'required',

    ]);

    if($validator->fails()) {
        flash($validator->errors)->error();
        return view('projects.create');
    }

    try {
        $project = $this->repository->store($request->all());
        flash('O projeto '. $project->name .' foi criado com sucesso!')->success();
        return redirect()->route('projects.show', ['id'=> $project->id]);
    } catch (\Exception $e) {
        flash($e->getMessage())->error();
        return view('projects.create');
    }
    dd($request);
}

When trying to register the data through the site I get the following error:

  

(2/2) ErrorException   Undefined variable: components (View: C: \ xampp \ htdocs \ thermopeu \ resources \ views \ projects \ create.blade.php)

It looks like a beast but I can not seem to get past it, the database is already working, including inserting a project manually by phpMyAdmin and making this project to the user.

What can I do to resolve this?

Below is the view as requested. It's a bit big, note that the component should be taken by the "side-bar":
