Registration Error

If I register an event listener and attach it to UserRegistered in sparkserviceproviders, then, when registering a new user at domain.com/register, it redirects to domain.com/undefined.

Some interesting things I noticed about this in the last 4 hours :(

inf Laravel\Spark\Http\Controllers\Auth\RegisterController;

    /**
     * Handle a registration request for the application.
     *
     * @param  RegisterRequest  $request
     * @return Response
     */
    public function register(RegisterRequest $request)
    {        
        dd("hi");
        Auth::login($user = Spark::interact(
            Register::class, [$request]
        ));

        event(new UserRegistered($user));

        return response()->json([
            'redirect' => $this->redirectPath()
        ]);
    }
}

...does NOT register a user, and serves up the /undefined error.. dd("hi) is nowhere to be found...

And..

    /**
     * Handle a registration request for the application.
     *
     * @param  RegisterRequest  $request
     * @return Response
     */
    public function register(RegisterRequest $request)
    {        

        Auth::login($user = Spark::interact(
            Register::class, [$request]
        ));

        dd("hi");
        event(new UserRegistered($user));

        return response()->json([
            'redirect' => $this->redirectPath()
        ]);
    }
}

...successfully registers a new user in the DB, but still redirects to /undefined, nobody said hi.

and finally if I do

        Auth::login($user = Spark::interact(
            Register::class, [$request]
        ));

        event(new UserRegistered($user));

        dd("hi");

        return response()->json([
            'redirect' => $this->redirectPath()

and....

        Auth::login($user = Spark::interact(
            Register::class, [$request]
        ));

        event(new UserRegistered($user));

    return 'hey';

        return response()->json([
            'redirect' => $this->redirectPath()

Still. registers a user, but I end up at /undefined again. No dd dump screen at all.

I feel like the answer is here somewhere... I did manage to find the point at which dd("hi") actually says hi, it is pretty deep in httpexception classes, I forget exaclty where now.

MY QUESTION

I suppose I could fix this, just, don't use events on register.

Maybe I'm doing something wrong in the events... but, I tested just putting dd("hi") in my events, and they DO NOT show up.

<?php

namespace App\Providers;



use Illuminate\Foundation\Support\Providers\EventServiceProvider as ServiceProvider;

class EventServiceProvider extends ServiceProvider
{
    /**
     * The event listener mappings for the application.
     *
     * @var array
     */
    protected $listen = [
        // User Related Events...
        'Laravel\Spark\Events\Auth\UserRegistered' => [            
            'Laravel\Spark\Listeners\Subscription\CreateTrialEndingNotification',                   

    //MY EVENT
            'App\Listeners\SendRegistrationEmails',            
            
        ],
    
...

And, for good measure...

<?php

namespace App\Listeners;

use Auth;
use Mail;
use Carbon\Carbon;
use App\Mail\ConfirmEmail;
use App\Mail\UserRegister;
use App\RegistrationConfirmation;
use App\Mail\SponsorSaleNotification;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
use Laravel\Spark\Events\Auth\UserRegistered;

class SendRegistrationEmails
{
    /**
     * Create the event listener.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Handle the event.
     *
     * @param  UserRegistered  $event
     * @return void
     */
    public function handle(UserRegistered $event)
    {       

        // add a new link to confirm table
        RegistrationConfirmation::create([
            'email' => $event->user->email,
            'token' => str_random(32),   
            'created_at' => Carbon::now(),         
            ]);

        dump("In send register email listener, sending confirm email, welcome email and sponsor notif email");


        Mail::to($event->user)->send(new UserRegister($event->user));
        // sleep(1);
        Mail::to($event->user)->send(new ConfirmEmail($event->user)); 
        // sleep(1);
        Mail::to($event->user)->send(new SponsorSaleNotification($event->user)); 

               

        // Mail::to($this->user())->queue($this->UserRegister());
        //use user-registered framework to send it?
        
    }
}

All of this works, I get the emails, the new table row is inserted, it's all good.

But . ARGH. my users getting sent to /undefined is not cool.

Help please if you know.

Thanks.
