We have a site ready to go live and I'm scrolling through the error log. I've run across this- Is there any way I can determine what product it is? Without knowing that, it looks like an AC bug since it's not custom code. An error has occured at http://elephantac9.web2m...n/Product/ProductDetails View less Exception: Object reference not set to an instance of an object. Stack Trace: at AbleCommerce.Areas.Admin.Controllers.ProductController.ProductDetails(EditProductModel editProductModel) at lambda_method(Closure , ControllerBase , Object[] ) at System.Web.Mvc.ReflectedActionDescriptor.Execute(ControllerContext controllerContext, IDictionary`2 parameters) at System.Web.Mvc.ControllerActionInvoker.InvokeActionMethod(ControllerContext controllerContext, ActionDescriptor actionDescriptor, IDictionary`2 parameters) at System.Web.Mvc.Async.AsyncControllerActionInvoker.b__39(IAsyncResult asyncResult, ActionInvocation innerInvokeState) at System.Web.Mvc.Async.AsyncResultWrapper.WrappedAsyncResult`2.CallEndDelegate(IAsyncResult asyncResult) at System.Web.Mvc.Async.AsyncControllerActionInvoker.EndInvokeActionMethod(IAsyncResult asyncResult) at System.Web.Mvc.Async.AsyncControllerActionInvoker.AsyncInvocationWithFilters.b__3d() at System.Web.Mvc.Async.AsyncControllerActionInvoker.AsyncInvocationWithFilters.<>c__DisplayClass46.b__3f() at System.Web.Mvc.Async.AsyncControllerActionInvoker.AsyncInvocationWithFilters.<>c__DisplayClass46.b__3f() at System.Web.Mvc.Async.AsyncControllerActionInvoker.EndInvokeActionMethodWithFilters(IAsyncResult asyncResult) at System.Web.Mvc.Async.AsyncControllerActionInvoker.<>c__DisplayClass21.<>c__DisplayClass2b.b__1c() at System.Web.Mvc.Async.AsyncControllerActionInvoker.<>c__DisplayClass21.b__1e(IAsyncResult asyncResult) at System.Web.Mvc.Async.AsyncControllerActionInvoker.EndInvokeAction(IAsyncResult asyncResult) at System.Web.Mvc.Controller.b__1d(IAsyncResult asyncResult, ExecuteCoreState innerState) at System.Web.Mvc.Async.AsyncResultWrapper.WrappedAsyncVoid`1.CallEndDelegate(IAsyncResult asyncResult) at System.Web.Mvc.Controller.EndExecuteCore(IAsyncResult asyncResult) at System.Web.Mvc.Async.AsyncResultWrapper.WrappedAsyncVoid`1.CallEndDelegate(IAsyncResult asyncResult) at System.Web.Mvc.Controller.EndExecute(IAsyncResult asyncResult) at System.Web.Mvc.MvcHandler.b__5(IAsyncResult asyncResult, ProcessRequestState innerState) at System.Web.Mvc.Async.AsyncResultWrapper.WrappedAsyncVoid`1.CallEndDelegate(IAsyncResult asyncResult) at System.Web.Mvc.MvcHandler.EndProcessRequest(IAsyncResult asyncResult) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStepImpl(IExecutionStep step) at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

It's hard to understand where the issue is without debugging. Do you have an opportunity to debug the source code:
Admin ProductController ProductDetails function?
The error is happening when saving the changes on the Edit Product screen. You will not be seeing a success message if this error occurs. This way you can look for the product id.

No, I can't debug it since it is a remote site. I didn't get the error on my local site.

ProductDetails action is only used from EditProduct screen and when you save the product details. It could be be happening if somehow product id is null, I wonder if there is an customization made on this screen that can possibly submit it without product id? Can you please copy/paste full error details from app log file? Edited by user Tuesday, November 17, 2020 2:02:10 AM(UTC)

I'm sorry, I can't post the details from the app.log. For some reason, we can't download the current. app.log via ftp on our servers. The only change to the edit product page was sorting the manufacturers alphabetically. Don't worry about it for now. I think I was partly just whining about all the gibberish in the error log entries, but I guess that is how MVC does it.
