NSC | REST WS: Empty External ID

When working with NetSuite's REST API, attempting to set a record's External ID to an empty string can lead to unexpected behavior. Instead of successfully updating the External ID field, the API responds with a

{
  "type": "XXX",
  "title": "Bad Request",
  "status": 400,
  "o:errorDetails": [
    {
      "detail": "Invalid value '' for the field externalid.",
      "o:errorPath": "externalid",
      "o:errorCode": "INVALID_VALUE"
    }
  ]
}

In conclusion, while NetSuite's REST API offers extensive capabilities for interacting with NetSuite data, developers must be mindful of constraints such as the inability to set External IDs to empty strings.
