Not able to create product with select type attribute

I am trying to create a product having select type attribute using product api.
I am using sylius Admin API for creating product. I am using Base URI /api/v1/products for the same.

Here, tshirt_style’ is select type attribute which I have already exported to the store.

The body of my request:

{
        "code": "test_product",
        "attributes": [
            {
                "attribute": "tshirt_style",
                "value": "V neck",
                "localeCode": "en_US"
            },
            {
                "attribute": "tshirt_style",
                "value": "V-Ausschnitt",
                "localeCode": "de"
            },
            {
                "attribute": "tshirt_style",
                "value": "Col en V",
                "localeCode": "fr"
            },
            {
                "attribute": "test_text",
                "value": "check",
                "localeCode": "en_US"
            }
        ],
        "options": [],
        "associations": [],
        "translations": {
            "en_US": {
                "name": "test_product",
                "slug": "test_product",
                "description": "test_product description"
            }
        },
        "channels":["FASHION_WEB"]
    }

In response, I am getting the following validation error:
