关于api11后，new抽象类问题有懂的吗？

public callback<T>(callback: AbstractResponse<T>) {

}
export abstract class AbstractResponse<T> {
  abstract success(result: T): void;

   fail?(error: Error): void {
     IToast.showToast(error?error.message:'网络异常')
  }
}
//这个写法在api11一直报错，之前api9都正常
Object literal must correspond to some explicitly declared class or interface (arkts-no-untyped-obj-literals) <ArkTSCheck>
很奇怪，这个怎么写出生命类
this.callback({
  success: (result: string) => {
    console.log("Success: " + result);
  },
  fail: (error: Error) => {
    console.error("Failed: " + error);
  }
});

class ConcreteResponse extends AbstractResponse<string> {
  success(result: string): void {
    console.log("Success: " + result);
  }
  fail(error: Error): void {
    console.error("Failed: " + error);
  }
}

this.callback(new ConcreteResponse())
