Description
The ASP.NET framework derives a JsonTypeInfo<object> for use in the serialization of filter functions that can return any object type. When used in serialization with a JsonContext, the JsonTypeInfo<object> throws an unhandled exception to the user.
Reproduction Steps
using System.Text.Json.Serialization;
var builder = WebApplication.CreateBuilder(args);
builder.Services.ConfigureHttpJsonOptions(o => o.SerializerOptions.TypeInfoResolver = JsonContext.Default);
var app = builder.Build();
app.MapGet("/", () => "Hello World!")
.AddEndpointFilter(async (c, n) => {
var r = await n(c);
return Results.Ok(new Todo("Test todo", false));
});
app.Run();
public record Todo(string Name, bool IsCompleted);
[JsonSerializable(typeof(Todo))]
public partial class JsonContext : JsonSerializerContext
{ }Expected behavior
Serialization of the payload to complete successfully.
Actual behavior
System.NotSupportedException: JsonTypeInfo metadata for type 'System.Object' was not provided by TypeInfoResolver of type 'Microsoft.AspNetCore.Http.G...
System.NotSupportedException
JsonTypeInfo metadata for type 'System.Object' was not provided by TypeInfoResolver of type 'Microsoft.AspNetCore.Http.Generators.Tests.SharedTestJsonContext'. If using source generation, ensure that all root types passed to the serializer have been annotated with 'JsonSerializableAttribute', along with any types that might be serialized polymorphically.
