Hi, I need a complete callback URL for OAuth server-side. I'm setting up authentication in routes.tsx and the following window.location.origin gives me the error below. I have seen here (https://github.com/aspnet/JavaScriptServices/tree/dev/src/Microsoft.AspNetCore.SpaServices#server-side-prerendering) that one can pass in params from the MVC View ... but seems a bit convoluted. What is the solution to this?

    // Configure OAuth
    this.logingui = new OAuthLogin(clientId, domain, {
        auth: {
            redirectUrl: `**${window.location.origin}**/login`,
            responseType: 'token'
        }
    })

Error:
fail: Microsoft.AspNetCore.Diagnostics.ExceptionHandlerMiddleware[0]
An unhandled exception has occurred: Call to Node module failed with error: Prerendering failed because of error: ReferenceError: window is not defined
at new AuthService (C:_d\cl\ClientApp\dist\main-server.js:24373:30)
