var getCommoditiesInput = new GetCommoditiesInput();
// 出错代码
var commodities = await CommoditiesAppService.GetListByTenantAsync(tenantId, getCommoditiesInput);
Console.WriteLine($"Commodities count: {commodities.Count}");
}
catch (Exception ex) {
Console.WriteLine($"Error fetching commodities: {ex.Message}");

对。
DependsOn(typeof(AbpAutofacModule), typeof(AbpAutoMapperModule), typeof(AbpAspNetCoreMvcClientCommonModule), typeof(AbpAspNetCoreComponentsWebModule), typeof(AbpIdentityProDomainSharedModule), typeof(AbpIdentityHttpApiClientModule), typeof(QueuingServiceHttpApiClientModule), typeof(AbpHttpClientIdentityModelModule))] public class KkdQueuingServiceMauiModule : AbpModule {如下图，手工注入可以获取到啊。

或者自定义的一个类，替换了
ClientProxyBase？如何实现？ -

你好
Volo.Abp.Http.Client.ClientProxying.ClientProxyBase 中哪个对象是 null?
如何复现呢？

你能分享一个项目吗？ 我不太确定你的步骤。

hi
Update
MauiProgramto add.ConfigureContainer(new AbpAutofacServiceProviderFactory(new Autofac.ContainerBuilder()));will fix theNullReferenceExceptionnamespace Kkd.QueuingService.Maui; public static class MauiProgram { public static MauiApp CreateMauiApp() { var builder = MauiApp.CreateBuilder(); builder .UseMauiApp<App>() .ConfigureFonts(fonts => { fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular"); }) .ConfigureContainer(new AbpAutofacServiceProviderFactory(new Autofac.ContainerBuilder())); -
