Angular Unit testing - NullInjectorError: No provider for DatePipe

I am implementing unit test for a service which have a dependency(Injected) of two more services, here one of the injected service use the Angular DatePipe. so i am using angular Testbed to automate like below, I am getting "NullInjectorError: No provider for DatePipe!" exception when I run the test method.

import { DatePipe } from '@angular/common';
import { TestBed } from '@angular/core/testing';

import { RouterModule } from '@angular/router';
import { TranslateModule } from '@ngx-translate/core';
import { TaskDetailsService } from './task-details.service';

fdescribe('TaskDetailsService', () => {
let service: TaskDetailsService;

beforeEach(() => {
TestBed.configureTestingModule({
imports: [TranslateModule.forRoot(), RouterModule.forRoot([])],
providers: [TaskDetailsService, DatePipe],
});
service = TestBed.inject(TaskDetailsService);
});

fit('should be created', () => {
expect(service).toBeTruthy();
expect(service.getPlaceholder(2)).toBe('Find in failed tasks');
});
});
