Did som runs in some scenarios I have here and it's working as expected:
For old semconv:

{
    "name": "http.server.duration",
    "description": "Duration of HTTP server requests.",
    "unit": "ms",
    "data": {
        "data_points": [
            {
                "attributes": {
                    "http.scheme": "http",
                    "http.host": "127.0.0.1:8000",
                    "net.host.port": 8000,
                    "http.flavor": "1.1",
                    "http.method": "GET",
                    "http.server_name": "localhost:8000",
                    "http.status_code": 500,
                    "http.target": "/foobar"
                },
            }

For new semconv:

{
"name": "http.server.request.duration",
"description": "Duration of HTTP server requests.",
"unit": "s",
"data": {
    "data_points": [
        {
            "attributes": {
                "url.scheme": "http",
                "network.protocol.version": "1.1",
                "http.request.method": "GET",
                "http.route": "/foobar",
                "http.response.status_code": 500,
                "error.type": "500"
}
