Return response in default wrapper-CodePudding

I'm developing a Web API in ASP.NET. When I use:

return BadRequest( result.Errors );

The response is just an array of errors. For consistency, I want the errors to be wrapped in the same wrapper as other asp.net errors like below:

{
"type": "https://tools.ietf.org/html/rfc7231#section-6.5.1",
"title": "One or more validation errors occurred.",
"status": 400,
"traceId": "|803e532a-47325349ba863a12.",
"errors": {
    "Password": [
        "The Password field is required."
    ]
}
}

How to achieve this result?
