Value can't be blank error for list.single_line_text_field

[carlgilbert]

Hi

I am trying to post a metafield value for a field with the type list.single_line_text_field however I get an error.

I am testing this in Postman. This is the body of the message:

{

  "metafield": {

    "namespace": "specifications",

    "key": "models",

    "value": ["Ford", "BMW", "Fiat"],

    "type": "list.single_line_text_field"

  }

}

This is the response:

{

    "errors": {

        "value": [

            "can't be blank."

        ]

    }

}

This is my URL: https://[my API key]:[my API token]@[my_shop].myshopify.com/admin/api/2023-04/products/[product id]/metafields.json

I am using a POST request.  My headers include:

 - Content-Type = application/json

 - X-Shopify-Access-Token = My API token

What am I doing wrong here?
