😕

i was using the payment id from the creation event: `jffuztfumrVLqnZCdltvEdA4njSZY`

i used that to retrieve the payment via api explorer bc the `customer_id` was not in the original payload. i got: `8ZE7FH29YD1GZDPK0WMAJ3XB04`

code would be:

```auto
const response = await client.cardsApi.createCard({
    idempotencyKey: '5303bfbf-c0e2-4423-9f74-9d239473592c',
    sourceId: 'jffuztfumrVLqnZCdltvEdA4njSZY',
    card: {
      customerId: '8ZE7FH29YD1GZDPK0WMAJ3XB04'
    }
  });

```

same error:

```auto
{
  "errors": [
    {
      "category": "INVALID_REQUEST_ERROR",
      "code": "INVALID_CARD_DATA",
      "detail": "Invalid card data.",
      "field": "source_id"
    }
  ]
}

```
