Cannot create GrpcChannel in Uno Platform WebAssembly (System.NullReferenceException)

[t-sorger]

I am trying to do a sample of Uno Platform using gRPC-Web.

Therefore I got inspired by the content provided by this article. I followed the instructions of the article and created a BlazorApp which used a weather service with gRPC-Web. After that I also included an other service, the counter service, as seen in this gRPC-Web example.

After everthing was working, I added a Uno Platform WebAssembly app to replace the BlazorApp client.

Problem:

When trying to create a GrpcChannel the application gets a System.NullReferenceException.

The code snippet for creating the channel looks like this:

var baseUri = "https://localhost:44366";
var channel = GrpcChannel.ForAddress(baseUri, new GrpcChannelOptions());

This is the same code as used in the BlazorApp sample.

The sample code for the BlazorApp and the Uno Platform WebAssembly can be found in this repository.

Any idea/suggestion/help on how to fix this would be appreciated.

Thanks for the info! I'm guessing the error happened during server setup, but not specifically wrt to the grpc-web JS client? 😃
