ReactScriptLoadException: Error while loading "/dist/vendor.8435dc72.js": ReferenceError: 'TextEncoder' is not defined

Keep getting the referenced error when trying to SSR with a Webpack bundle. Copied the webpack config from the reactnet-webpack project.

Using: ChakraCoreJsEngine Win 64 Win 86

See Startup.cs and the exception detail below:

public class Startup { public Startup(IConfiguration configuration) { Configuration = configuration; }

    public IConfiguration Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc();

        services.AddJsEngineSwitcher(options => options.DefaultEngineName = ChakraCoreJsEngine.EngineName)
            .AddChakraCore();
        services.AddReact();
        services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
        services.AddControllersWithViews();
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {

        app.UseReact(config =>
        {
            config
                .SetReuseJavaScriptEngines(true)
                .SetLoadBabel(false)
                .SetLoadReact(false)
                .SetReactAppBuildPath("~/dist");
        });

        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
            // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
            app.UseHsts();
        }
        app.UseHttpsRedirection();
        app.UseStaticFiles();

        app.UseRouting();

        app.UseAuthorization();

        app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllerRoute(
                name: "default",
                pattern: "{controller=Home}/{action=Index}/{id?}");
        });
    }
}

}

Figured it out. Was trying to use react and react-dom 18. Had to downgrade the version.
