Web Api doesn't return exceptions

Question

I have a Web Api implementation (version 2.2) that doesn't throw any errors in the test environment.

If I run this method in dev

[HttpGet]
public HttpResponseMessage Fail()
{
    return Request.CreateErrorResponse(HttpStatusCode.InternalServerError, "I shall fail", new Exception("Exception message"));
}

It returns as supposed

In the other environment I only get

{"Message":"I shall fail"}

Any ideas where to start looking?

设置为Localonly是IncludeErrorDetailPolicy
