Library Version: 44.2.0

  const cards = await client.cards.list({
    customerId: squareCustomerId,
  });

Response

Body: {
  "errors": [
    {
      "category": "INVALID_REQUEST_ERROR",
      "code": "INVALID_ENUM_VALUE",
      "detail": "`` is not a valid enum value for `sort_order`.",
      "field": "sort_order"
    }
  ]
}

"rawResponse":{"headers":{},"redirected":false,"status":400,"statusText":"Bad Request","type":"basic","url":"https://connect.squareupsandbox.com/v2/cards?customer_id=<redacted>&sort_order="},

Expected behaviour

Not passing sortOrder should just return the default, presumably by just removing the &sort_order= query from the url when not provided.

Workaround

  const cards = await client.cards.list({
    customerId: squareCustomerId,
    sortOrder: 'DESC',
  });
