Azure web app unexpected crash

I have a web app which is running in Azure. When I try to debug it in VS, I can get as far as to var newResume = new Resume() {JobId = (int)jobid}; line (I get correct jobid), but then I get "server error" and page is redirected to error page. Everything works locally. What can be the problem? Thanks for your time

            [HttpGet]
            public ActionResult Create(int jobid)
            {
                var newResume = new Resume() {JobId = jobid};

                return View(newResume);
            }
