Login and verify user - Call to a member function getKey() on null

Question

I am trying to create a custom verification flow, where as soon as a user clicks the verification link, it logs him in and also verifies him, instead of first making him log in and only then the verification link works.

I built a custom notification URL in my CustomVerificationNotification, including the registered user_id, to login him later:

protected function verificationUrl($notifiable)
{
    if (static::$createUrlCallback) {
        return call_user_func(static::$createUrlCallback, $notifiable);
    }

    return URL::temporarySignedRoute(
        'verification.custom-verify',
        Carbon::now()->addMinutes(Config::get('auth.verification.expire', 60)),
        [
            'id' => $notifiable->getKey(),
            'hash' => sha1($notifiable->getEmailForVerification()),
            'user_id' => $this->user->id
        ]
    );
}

Then in my web.php I added this route:

Route::get('/email/verify/{id}/{hash}/{user_id}','Auth\CustomVerifyController@login_and_verify')->name('verification.custom-verify');

Then in my CustomVerifyController:

public function login_and_verify(EmailVerificationRequest $request)
{
    //..
}

But I get Call to a member function getKey() on null. And I can't edit EmailVerificationRequest, so what can I do? Is it possible to somehow call Auth::login($user); before calling the EmailVerificationRequest? (Because I have the user_id from the route)

I tried to follow the best answer from this post as well: How to Verify Email Without Asking the User to Login to Laravel

But I'm not sure then how to trigger the verify() method from the web.php and send the $request when I'm first calling the verify_and_login method
