Cashier ERROR: Method newSubscription() does not exist?

Question

Stripes

Here is my model:

namespace App\Entities;

use Illuminate\Database\Eloquent\Model;
use Prettus\Repository\Contracts\Transformable;
use Prettus\Repository\Traits\TransformableTrait;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Laravel\Cashier\Billable;
use Illuminate\Database\Eloquent\SoftDeletes;

class User extends Model implements Transformable
{

    use TransformableTrait, Notifiable, Billable, SoftDeletes;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
    'name',
    'email',
    'password',
    'account_type',
    'stripe_id',
    'card_brand',
    'card_last_four',
    'trial_ends_at',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
    'remember_token',
    ];
    protected $dates = [
    'trial_ends_at',
    'ends_at',
    ];
}

When registering, it passes validation, and I try to create a subscription. A subscription to stripe has been created.
Registration controller:

namespace App\Http\Controllers\Auth;

use App\Entities\User;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Validator;
use Illuminate\Foundation\Auth\RegistersUsers;

class RegisterController extends Controller
....

protected function create(array $data)
    {
        $stripeToken = $data['stripeToken'];
        $accountType = strtolower($data['account_type']);
        $user = User::create([
            'account_type' => $accountType,
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => bcrypt($data['password']),
            ]);
        $subscriber = User::where('email', $data['email'])->get();
        if($accountType == 'individual')
        {
             $subscriber->newSubscription('individual', 'individual')->create($stripeToken);
 // тут выкидывает ошибку
        }
        else
        {
            return 'NOT individual!!!';
        }
        return 'DONE!';
    }

Stripe in test mode, the token comes after submitting the form.

Answer 1

The question can be deleted, I looked at the function in the line:

$subscriber = User::where('email', $data['email'])->get();
//а надо 
$subscriber = User::where('email', $data['email'])->first();

Answer 2

Everything is described in the error itself. You don't have newSubscription() method and you are trying to call it.
