[AngularJS] Error: Invalid provider for the NgModule 'DynamicTestModule' - only instances of Provider and Type are allowed, got: [?[object Object]?, ...]

[Dev C]

Hello I am writing Unit test cases as below:

import { async, ComponentFixture, TestBed } from '@angular/core/testing';
import { Injectable, CUSTOM_ELEMENTS_SCHEMA, NO_ERRORS_SCHEMA } from
'@angular/core';
import { isPlatformBrowser } from '@angular/common';
import { By, BrowserModule } from '@angular/platform-browser';
import { MockBackend } from '@angular/http/testing';

import {Component, Directive, ChangeDetectorRef, Renderer2} from
'@angular/core';
import { NgbModal, NgbModule } from '@ng-bootstrap/ng-bootstrap';
import {showallResult} from './showall.component';
import {NgbActiveModal} from '@ng-bootstrap/ng-bootstrap';
import {SearchService} from '@backbase/commons';
import {ItemModel} from '@backbase/foundation-ang/core';
import { XHRBackend } from '@angular/http/src/backends/xhr_backend';
import { Subject, Observable } from 'rxjs';
import { mineModule} from 'libs/mine-portfolio/src/common.module';

class ItemModelStub {
  public mockValue = new Subject<string>();
  public property() {
      return this.mockValue as Observable<string>;
  }
}

fdescribe('showallResult', () => {


  let fixture;
  let component: any;
  let  itemModelStub;

  beforeEach(() => {
    const searchServiceStub = [{
      "lastPrice": {
        "currency": "EUR",
        "price": 123425.63,
        "date": "2019-12-27T09:05:28.368Z"
      },
    }]

     itemModelStub  = new ItemModelStub()
        const changeDetectorRefStub = { markForCheck: () => ({}) };
    TestBed.configureTestingModule({
      schemas: [CUSTOM_ELEMENTS_SCHEMA, NO_ERRORS_SCHEMA],
      declarations:[],
      providers: [
         { proivide: SearchService, useValue:searchServiceStub},
         { provide: ItemModel,useValue: itemModelStub },
         { provide: ChangeDetectorRef,useValue: changeDetectorRefStub },
      ],
      imports : [mineModule,BrowserModule, NgbModule.forRoot()],
    }).compileComponents();
    fixture = TestBed.createComponent(showallResult);
    component = fixture.componentInstance;
    fixture.detectChanges();
  });

I am getting error as below :
Error: Invalid provider for the NgModule 'DynamicTestModule' - only
instances of Provider and Type are allowed, got: [?[object Object]?, ...]
this is probably because of this line:
           { proivide: SearchService, useValue:searchServiceStub},

Can anyone please help me in this.
