How to increase Logging Detail when seeing `ManagedError: One or more errors occurred. (Operation is not supported on this platform.)

[thatstatsguy]

Hi there!

I'm currently experimenting with the Blazor Web App hosting model and playing around with different hosting models for my components.

Note on discussion below - I am unfortunately required to be very vague about code specifics

My solution up until now has always been a server side rendered blazor application. To test out the new features I've created a test application with dotnet new blazor --interactivity Auto

I've copied over the component from my blazor server application into the new application template within the .Client project.

Using <ComponentName @rendermode="InteractiveServer"/> for this component works 100%.

The problem arises when using @rendermode="new InteractiveWebAssemblyRenderMode(prerender: false)" or @rendermode="InteractiveWebAssembly" where I receive a very cryptic.

blazor.web.js:1 
 ManagedError: One or more errors occurred. (Operation is not supported on this platform.)

What I can say about my component

• It uses JS interop. I'm aware that one needs to rejig all JS interop calls to be synchronous calls and have done so as per here
• All .Net calls from Js have been converted to synchronous calls as well
• It doesn't make any HttpClient calls which have created similar errors as mentioned here and here It makes a grpc web call via an injected service

Question
Is there any way one can "switch up" the logging to better understand what's amiss? Currently my debugger only hits some test code I've written in OnInitialized and then shortly bombs out after that

protected override void OnInitialized()
    {
        Console.WriteLine("Here");
    }

Other potentially useful info

• Windows 11 machine
• Testing on latest version of edge
• Using Rider for debugging
• Running on dotnet 9.0.100

Update:
I've deleted pretty much everything in the component. I've narrowed down the issue to a specific service I'm injecting.

[Inject]
    public ISpecialService { get; set; }

ISpecialService is implmented in SpecialService which makes grpcweb calls to an external api.

Just to make sure it's not something async causing an issue I re-jigged everything to be synchronous instead of async. Still the same issue persists.

I'm registering the grpc service as

services
            .AddGrpcClient<ProtoClient>(options =>
            {
                options.Address = new Uri(someEndpoint);
            })
            .ConfigurePrimaryHttpMessageHandler(() => GetHandlerNoDevServerCertValidation())

where
GetHandlerNoDevServerCertValidation is a function used in development to trust certs and make life a bit easier

private static HttpClientHandler GetHandlerNoDevServerCertValidation()
    {
        return new HttpClientHandler
        {
            ServerCertificateCustomValidationCallback =
                HttpClientHandler.DangerousAcceptAnyServerCertificateValidator,
        };
    }

Update 2: This appears to be what's causing the issue. The warning makes sense, but I'm curious how one could get to this without needing to go through all the above steps
