Blazor WASM exclude external routes

[jrmurdoch]

I'm hosting Blazor WASM spa on Azure Static Web Apps, the api/* & .auth/* routes are special routes that are picked up and handled by Asure Static Web Apps. My Blazor app handles these., how can I exclude these from being handled by Blazor?

TLDR;

Demo app hosted here: https://orange-grass-0a3e6ff10.5.azurestaticapps.net/
There are 3 login links on the site for testing, they all link or redirect to: https://orange-grass-0a3e6ff10.5.azurestaticapps.net/.auth/login/aad

When the "Log in 2" is clicked for example

<a href="/.auth/login/aad">Log in 2</a>

(Annoyingly) Blazor catches this route and returns "Not Found", "Sorry, there's nothing at this address." this comes from App.razor

<CascadingAuthenticationState>
    <Router AppAssembly="@typeof(App).Assembly">
        <Found Context="routeData">
            <AuthorizeRouteView RouteData="@routeData" DefaultLayout="@typeof(MainLayout)">
                <Authorizing>
                    <p>Loading session state...</p>
                </Authorizing>
                <NotAuthorized>
                    <h1>Sorry</h1>
                    <p role="alert">You are not authorized to access this resource.</p>
                </NotAuthorized>
            </AuthorizeRouteView>
            <FocusOnNavigate RouteData="@routeData" Selector="h1" />
        </Found>
        <NotFound>
            <PageTitle>Not found</PageTitle>
            <LayoutView Layout="@typeof(MainLayout)">
                <p role="alert">Sorry, there's nothing at this address.</p>
            </LayoutView>
        </NotFound>
    </Router>
</CascadingAuthenticationState>

The url of the browser is now pointing to: https://orange-grass-0a3e6ff10.5.azurestaticapps.net/.auth/login/aad

CTRL+F5 to do a refresh and url is picked up by Azure Static Web Apps rather than Blazor now and redirects to the correct login flow.

How can I avoid the Blazor route processing on api/* & .auth/* so these fall back to processing by Azure Static Web Apps?

P.S. I have it work once without a CTRL+F5 refresh but never again....

I found the problem and will post here in case anyone else is having the same issue. Its was all down to me making a silly comment in the appsettings.json, as json doens't support comments the file was incorrect,

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  }
  //"AzureAd": {
  //  "ClientId": "562344d4-b093-4ddf-8b3d-XXXXXXXX",
  //  "Authority": "https://cusers.ciamlogin.com/cusers.onmicrosoft.com",
  //  //"Authority": "https://login.microsoftonline.com/aXXXXXX-e6a1-4f1b-baeb-604c7b67d2f2",
  //  "ValidateAuthority": true
  //}
}
