Minimal repro without Convey:

var builder = WebApplication.CreateBuilder(args);

var sp = build.Services.BuildServiceProvider();
_ = sp.GetRequiredService<IConfiguration>();
sp.Dispose();

var app = builder.Build();

Edit: You can likely workaround the issue by passing builder.Configuration to AddConvey()

builder.Services.AddConvey(configuration: builder.Configuration);

Looks like the issue isn’t related to only the WebApplicationFactory. The exception is also thrown at runtime.

If that’s your scenario it’s covered by my initial comment #40614 (comment) and is fixed in a change coming in 6.0.4

Cool, thanks for your help!
