## 🐛 Describe the Bug

When pass the country as “RS”, the api returns 400 error code.

```auto
{
  "error": {
    "message": "Validation error: country must be provided as a valid 2-digit ISO country code, got RS",
    "type": "invalid_country_code",
    "code": 400
  }
}

```

But RS is indeed a valid ISO 3166-1 alpha-2 country code for Serbia.
