getCustomer exception ? could be better if returns null (i think)

[rycks]

Il some race conditions there is a problem with php lib, for example when stancer server returns that sort of data:

    {
      "amount": 100,
      "auth": null,
      "capture": true,
      "country": "FR",
      "created": 1681876445,
      "currency": "eur",
      "date_bank": 1681855200,
      "date_paym": 1681768800,
      "description": null,
      "fee": 2,
      "id": "paym_sqxxxxxxxxxxxxxxxxxxx",
      "method": "card",
      "order_id": null,
      "response": "00",
      "status": "captured",
      "unique_id": "xxxxxxxxxxx"
    },

Then, if i call $payment->getCustomer() result is "Stancer\Exceptions\Exception exception occurs : Missing card details" but the documentation says that function will return Stancer\Customer or null
