Description
Describe the bug
The ExceptionHandlerExtensions class offers several extension methods for using the ExceptionHandlerMiddleware but the usage of its extension method without parameters causes the InvalidOperationException occurs.
To Reproduce
- Create ASP.NET Core Web Application.
- Call UseExceptionHandler() method on the IApplicationBuilder in the Configure method in the Startup.cs file.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
app.UseExceptionHandler();
...
}The exception:
System.InvalidOperationException: 'An error occurred when configuring the exception handler middleware. Either the 'ExceptionHandlingPath' or the 'ExceptionHandler' option must be set in 'UseExceptionHandler()'.'
