Product custom attributes not updated - Magento 2 REST API

Question

I'm using Magento 2.3.4 CE. I used the below JSON to update the product custom attribute part_number in swagger.

{
  "product": {
    "sku": 678899,
    "name": "Product name",
    "attribute_set_id": "4",
    "price": 2.93,
    "status": "1",
    "visibility": 0,
    "type_id": "simple",
    "weight": 0,
    "extension_attributes": {
      "stock_item": {
        "qty": 10,
        "is_in_stock": true
      }
    },
    "custom_attributes": [
      {
        "attribute_code": "part_number",
        "value": "123456"
      }
    ]
  }
}

And I get 200 success response but when I checked in admin and catalog_product_entity_varchar table I don't see the custom attribute part_number value updated.

I have checked with both PUT and POST method but it is not updated part_number

PUT http://127.0.0.1/default/m234/rest/all/V1/products/678899

POST http://127.0.0.1/default/m234/rest/all/V1/products

I have seen known issues https://github.com/magento/magento2/issues/4527 but I didn't see the proper solution.
