src/Serval.Shared/Controllers/HttpResultFilter.cs line 16 at r1 (raw file):

        public override Task OnResultExecutionAsync(ResultExecutingContext context, ResultExecutionDelegate next)
        {
            if (context.Result is ObjectResult r && r.StatusCode / 100 > 3)

PEMDAS makes my head spin - and is it int or float math? How about:
if ((context.Result is ObjectResult r) && (r.StatusCode >= 400))?

Haha, sure. I can do that. I think I even switched it to a ">= 400" but must have control-z-ed.
