Give a try on the following payload

{
  "product": {
    "sku": "samsung-a50",
    "name": "Samsung A50 ",
    "attribute_set_id": 4,
    "price": 150000,
    "status": 1,
    "visibility": 1,
    "type_id": "simple",
    "weight": "1",
    "extension_attributes": {
      "category_links": [
        {
          "position": 0,
          "category_id": "2"
        }
      ],
      "stock_item": {
        "qty": "10",
        "is_in_stock": true
      }
    },
    "custom_attributes": [
      {
        "attribute_code": "pattern",
        "value": "1960"
      },
      {
        "attribute_code": "color",
        "value": "45"
      },
      {
        "attribute_code": "size",
        "value": "168"
      }
    ]
  }
}

"type_id": "simple" and "category_id": "2" should be greater or equal than 2 (2 is the of category id comes by default in case unless someone has changed).

Do not pass category_id as 0
