ObjectResult StatusCode 500 be overwritten in production enviroment

Question

I'm integrating an ASP.NET Core 6 MVC website.

We have a jQuery ajax post call

$.ajax({
    type: 'POST',
    url: url, // Patch
    data: { "dict": JSON.stringify(dict) }
}).done(function (response) {
    $('#resultSection').css('display', '');
    $('#errorModal').modal('hide');

}).fail(function (jqXHR, textStatus, errorThrown) {
    console.log(jqXHR);
    $('#errorMessage').html(jqXHR.responseJSON.message);
    $('#errorSection').css('display', '');
    $('#errorModal').modal('hide');
    var errSection = document.getElementById('errorSection');
    errSection.scrollIntoView();
});

The method it calls can be simplified as

public IActionResult Patch(string dict)
{
    try
    {   
        var list = JsonConvert.DeserializeObject<List<KeyValuePair<string, string>>>(dict);
        // list => dicKeyPartNumberPairs
        _dao.InsertDigitalAttaches(dicKeyPartNumberPairs);

        return StatusCode(200, new BasicResponse
        {
            isSuccess = "1",
            message = "Import Completed"
        });
    }
    catch (Exception ex)
    {
        _logger.LogError(ex.Message);

        return StatusCode(500, new BasicResponse
        {
            isSuccess = "0",
            message = "An unexpected error occurs, please, reach out to ..."
        }); 
    }
}

public class BasicResponse
{
    public string? isSuccess { get; set; }
    public string message { get; set; }
}

When we test Patch with Visual Studio, no matter return 200 or 500 the corresponding done and fail function can be conducted correctly.

However, when we publish this to windows server 2019 + IIS 10. If we return 500, the StatusCode object seems to be replaced by a fixed formatted content that leads our fail function out of order.

Running Visual Studio, the response I got is

What can I do to make BasicResponse pass to client as it works with Visual Studio? Or is there a way at least I can pass message?
