Problem When Create a Response to a Customer Review on Apple Store Connect API

Hi, I'm trying to create a response for a review through the Apple Store Connect API, but I receive the following error message when sending the body following this documentation: https://developer.apple.com/documentation/appstoreconnectapi/create_or_update_a_response_to_a_customer_review

cURL Request

--header 'Authorization: {{MY_BEARER_TOKEN}}' \
--header 'Content-Type: application/json' \
--data '{
    "attributes": {
        "responseBody": "{{MY_RESPONSE}}"
    },
    "relationships": {
        "review": {
            "data": {
                "id": "{{REVIEW_ID}}",
                "type": "customerReviews"
            }
        }
    },
    "type": "customerReviewResponses"
}'

*I changed the cURL to not display real data, but they are filled in my request.

Error message:

    "errors": [
        {
            "id": "5575b9ef-9005-4db2-9a89-123b1aaa9355",
            "status": "422",
            "code": "ENTITY_UNPROCESSABLE",
            "title": "The request entity is not a valid request document object",
            "detail": "Unexpected or invalid value at 'attributes'.",
            "meta": {
                "position": {
                    "row": 2,
                    "column": 20
                }
            }
        }
    ]
}

Can you help me put together the body correctly if that's the case of the error?
