I'm getting this BindingResolutionException in Laravel

[llevvi]

Hello,
This is probably not an issue in the optimus class itself. I must be doing something silly or forgetting to do something.

I have this controller called "VendorsControllers" where I inject Optimus in the constructor. When I try to go to the index page I get this:

BindingResolutionException in Container.php line 850:
Unresolvable dependency resolving [Parameter #0 [ <required> $prime ]] in class Jenssegers\Optimus\Optimus

Here's an snippet of my controller:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;

use App\Vendor;

use Auth;

use Jenssegers\Optimus\Optimus;

class VendorController extends Controller
{

    protected $optimus;

    public function __construct(Optimus $opt)
    {
        $this->optimus = $opt;
    }

    public function index()
    {
        $user = Auth::user();
        $vendors = Vendor::with('user')->get();

        foreach($vendors as $key => $vendor){
          $vendor->id = $this->optimus->encode($vendor->id);
          $vendors[$key] = $vendor;
        }

        return view('vendors/index', compact('vendors'));
    }

And here's my Optimus service provider:

<?php

namespace App\Providers;

use Jenssegers\Optimus\Optimus;
use Illuminate\Support\ServiceProvider;

class OptimusServiceProvider extends ServiceProvider
{
    public function register()
    {
        $this->app->singleton(Optimus::class, function ($app) {
            return new Optimus(2123809381, 1885413229, 146808189);
        });
    }
}

Should I register this service provider? I wasn't sure if it was really needed since Optimus documentation doesn't mention that.

Thanks in advance.

Well, the issue was what I suspected. The service provider has to be added to the providers array in config/app.php:

App\Providers\OptimusServiceProvider::class,

Sorry, I should've tested this before I opened the issue. At least it will be registered here for those who make the same mistake in the future. I'm also gonna do a pull request to include it on your documentation.
