API not accepting body from Documentation on Endpoint POST: /api/catalog_system/pvt/products/{productId}/specification

Greetings everyone!
I am making a change to a product specification via API at the Endpoint:
/api/catalog_system/pvt/products/{productId}/specification
And the body listed in the documentation is not accepted by the API.
Below is the example provided in the documentation followed by the error returned.

[
    {
        "Value": [
            "Iron",
            "Plastic"
        ],
        "Id": 30,
        "Name": "Material"
    }
]

Cannot deserialize the current JSON array (e.g. [1,2,3]) into type ā€˜VTEX.Commerce.CatalogApi.Web.Catalog.ProductFieldValueDto’ because the type requires a JSON object (e.g. {ā€œnameā€:ā€œvalueā€}) to deserialize correctly.

Would anyone know the correct way to send the request body?

I ran a test here with values similar to those in the documentation, and it worked.

  1. First, I made a GET request to check the existing values:
curl --location --request GET 'https://{{accountName}}.vtexcommercestable.com.br/api/catalog_system/pvt/products/1/specification' \
--header 'VtexIdclientAutCookie: {{cookie}}' \
--header 'Content-Type: application/json' \
--data '[
    {
        "Value": [
            "Wavy"
        ],
        "Id": 18,
        "Name": "Curl Type"
    }
]'
  1. Then, I made a POST request adding a new value to a spec:
curl --location 'https://{{accountName}}.vtexcommercestable.com.br/api/catalog_system/pvt/products/1/specification' \
--header 'VtexIdclientAutCookie: {{cookie}}' \
--header 'Content-Type: application/json' \
--data '[
    {
        "Value": [
            "Wavy",
            "Curly"
        ],
        "Id": 18,
        "Name": "Curl Type"
    }
]'
  1. Then, GET again:
curl --location 'https://{{accountName}}.vtexcommercestable.com.br/api/catalog_system/pvt/products/1/specification' \
--header 'VtexIdclientAutCookie: {{cookie}}' \
--data ''

The response from the last one included the new value I added, so it seems to have worked:

[
    {
        "Value": [
            "Anti-Frizz"
        ],
        "Id": 19,
        "Name": "Benefit"
    },
    {
        "Value": [
            ""
        ],
        "Id": 21,
        "Name": "Eco-Friendly"
    },
    {
        "Value": [
            "Wavy",
            "Curly"
        ],
        "Id": 18,
        "Name": "Curl Type"
    }
]
