HTTP code does not match error/code one

[Benjamin-Loison]

curl 'http://localhost/YouTube-operational-API/search' -D -

Output:

HTTP/1.1 200 OK
Date: Mon, 28 Oct 2024 14:46:53 GMT
Server: Apache/2.4.58 (Ubuntu)
Access-Control-Allow-Origin: *

{
    "error": {
        "code": 400,
        "message": "Required parameters not provided"
    }
}

Can it be seen as a feature? What if it's not a constant part that is the issue but a varying one such as a video id?
