Current behavior:

Making a POST request to /profileparameters with no body in the request returns:

HTTP/1.1 500 Internal Server Error
{
    "alerts": [
        {
            "text": "Internal Server Error",
            "level": "error"
        }
    ]
}

Expected / new behavior:

Most endpoints return:

HTTP/1.1 400 Bad Request 
{
    "alerts": [
        {
            "text": "EOF",
            "level": "error"
        }
    ]
}
