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
