object ref error with WebMarkupMin.AspNetCore7.

Hi

I noticed this error in my log today and wondered if anyone knows what it means? I am using WebMarkupMin.AspNetCore7 in .Net 7 Razor pages app. It happened on a web hook handler that receives posts from Stripe. Any ideas?

System.NullReferenceException: Object reference not set to an instance of an object. at Bayleaf.Pages.WebHooks.ProcessPaymentModel.OnPost() in C:\Users\jim\Source\Repos\Bayleaf\Pages\WebHooks\ProcessPayment.cshtml.cs:line 245 at Microsoft.AspNetCore.Mvc.RazorPages.Infrastructure.ExecutorFactory.GenericTaskHandlerMethod.Convert[T](Object taskAsObject) at Microsoft.AspNetCore.Mvc.RazorPages.Infrastructure.ExecutorFactory.GenericTaskHandlerMethod.Execute(Object receiver, Object[] arguments) at Microsoft.AspNetCore.Mvc.RazorPages.Infrastructure.PageActionInvoker.InvokeHandlerMethodAsync() at Microsoft.AspNetCore.Mvc.RazorPages.Infrastructure.PageActionInvoker.InvokeNextPageFilterAsync() at Microsoft.AspNetCore.Mvc.RazorPages.Infrastructure.PageActionInvoker.Rethrow(PageHandlerExecutedContext context) at Microsoft.AspNetCore.Mvc.RazorPages.Infrastructure.PageActionInvoker.Next(State& next, Scope& scope, Object& state, Boolean& isCompleted) at Microsoft.AspNetCore.Mvc.RazorPages.Infrastructure.PageActionInvoker.InvokeInnerFilterAsync() at Microsoft.AspNetCore.Mvc.Infrastructure.ResourceInvoker.gAwaited|25_0(ResourceInvoker invoker, Task lastTask, State next, Scope scope, Object state, Boolean isCompleted) at Microsoft.AspNetCore.Mvc.Infrastructure.ResourceInvoker.Rethrow(ResourceExecutedContextSealed context) at Microsoft.AspNetCore.Mvc.Infrastructure.ResourceInvoker.Next(State& next, Scope& scope, Object& state, Boolean& isCompleted) at Microsoft.AspNetCore.Mvc.Infrastructure.ResourceInvoker.g__Awaited|20_0(ResourceInvoker invoker, Task lastTask, State next, Scope scope, Object state, Boolean isCompleted) at Microsoft.AspNetCore.Mvc.Infrastructure.ResourceInvoker.gAwaited|17_0(ResourceInvoker invoker, Task task, IDisposable scope) at Microsoft.AspNetCore.Mvc.Infrastructure.ResourceInvoker.gAwaited|17_0(ResourceInvoker invoker, Task task, IDisposable scope) at Microsoft.AspNetCore.Routing.EndpointMiddleware.g__AwaitRequestTask|6_0(Endpoint endpoint, Task requestTask, ILogger logger) at Microsoft.AspNetCore.Session.SessionMiddleware.Invoke(HttpContext context) at Microsoft.AspNetCore.Session.SessionMiddleware.Invoke(HttpContext context) at Microsoft.AspNetCore.Authorization.AuthorizationMiddleware.Invoke(HttpContext context) at Microsoft.AspNetCore.Authentication.AuthenticationMiddleware.Invoke(HttpContext context) at WebMarkupMin.AspNetCore7.WebMarkupMinMiddleware.InvokeCore(HttpContext context, Boolean useMinification, Boolean useCompression) at WebMarkupMin.AspNetCore7.WebMarkupMinMiddleware.InvokeCore(HttpContext context, Boolean useMinification, Boolean useCompression) at Microsoft.AspNetCore.Diagnostics.ExceptionHandlerMiddlewareImpl.gAwaited|8_0(ExceptionHandlerMiddlewareImpl middleware, HttpContext context, Task task)

Hello, Gus!

It can be seen from the stack trace that this error did not occur in the WebMarkupMin Middleware.

Look at the code that is on line 245 of the Pages\WebHooks\ProcessPayment.cshtml.cs file.

If you think that the error is caused by the WebMarkupMin, then try to reproduce this error in the form of demo project and send me a link to it.

Thanks. I'll re-factor the code and see if I can work out what was happening.
