HttpClient BaseAddress

[marcelagraz]

I was having this error:

crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
      Unhandled exception rendering component: An invalid request URI was provided. Either the request URI must be an absolute URI or BaseAddress must be set.

I had to add:

services.AddHttpClient<GraphQLHttpClient>("GraphQLHttpClient", client => 
{ 
    if (client is not null) 
        client.BaseAddress = new Uri(builder.HostEnvironment.BaseAddress + "graphql"); 
});

services.AddSmartGraphQLClient();

to get the client working in a Blazor wasm app.

Is there any other way of setting up the HttpClient BaseAddress?

Thanks
