API "Done" and "Success" Event not firing for some APIs in Client Side API

My App Connect API Form is running the API on pressing submit button and my server (Azure Functions) logs show that everything worked as expecte d , but in Wappler the Done event is only firing for some functions. Is there some kind of time limit within which response has to be received because the <1sec are firing the done event correctly but the ~3sec ones are not

Thanks

Feels like a bug in the client side API Done Event

It seems to fire reliably for all codes between 400 to 500 and but never fires for codes in the 200 series ( like 200 , 201 , 202…)

Please let me know if i am doing something wrong or if this is a bug and if there are any workaround Thanks

public static class Function1
    {
        [FunctionName("Function1")]
        public static async Task<IActionResult> Run(
            [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
            ILogger log)
        {
            log.LogInformation("C# HTTP trigger function processed a request.");

            string name = req.Query["name"];

                log.LogInformation( name);
            
            switch(name)
            {
                case "200":
                        return (ActionResult) new StatusCodeResult(200);


                case "201":
                    return (ActionResult)new StatusCodeResult(201);

                case "202":
                    return (ActionResult)new StatusCodeResult(202);

                case "210":
                    return (ActionResult)new StatusCodeResult(210);

                case "211":
                    return (ActionResult)new StatusCodeResult(211);

                case "212":
                    return (ActionResult)new StatusCodeResult(212);

                case "220":
                    return (ActionResult)new StatusCodeResult(220);

                case "250":
                    return (ActionResult)new StatusCodeResult(250);

              
                case "400":
                    return (ActionResult)new StatusCodeResult(400);

                case "410":
                    return (ActionResult)new StatusCodeResult(410);

                case "411":
                    return (ActionResult)new StatusCodeResult(411);

                case "412":
                    return (ActionResult)new StatusCodeResult(412);

                case "420":
                    return (ActionResult)new StatusCodeResult(420);

                case "421":
                    return (ActionResult)new StatusCodeResult(421);

                case "501":
                    return (ActionResult)new StatusCodeResult(501);

                case "502":
                    return (ActionResult)new StatusCodeResult(502);

               
                default:

                    return (ActionResult)new StatusCodeResult(550);
            }
           
        }
    }
}

I tried the above API to find this out

Form Code is

<form id="form1" is="dmx-api-form" action="https://xxx.azurewebsites.net/api/
Function1?code=IAx6SnN0/XnfwxQARnOQnh1A==" 
dmx-on:done="run({alert:{message:`form1.status +\'status\'`}})" 
name="name.value">
         <input id="name" name="name" type="text" class="form-control">
          <button id="btn2" class="btn" type="submit">Button</button>
                </form>

Edited to Add, that There is the same problem with Success Event too

For Codes in the 200 series
the following works

case "210":
                    return new ObjectResult("this works") { StatusCode = 210 };

and the following do not work

 case "210":
                    return (ActionResult)new StatusCodeResult(210);
 case "210":
                    return new StatusCodeResult(210);

For Codes in the series 400-599 all of the above work
