'NgbModal error when trying to close

I've successfully imtegrated the NgbModal into my Angular 2 application, I currently have another component being shown within the modal.

The issue I have is once it's appeared and I click close I get the following error message:

Cannot read property 'close' of undefined

Now I've been following Components as content I've looked at the HTML and also gone through the Typescript, however I'm unsure what I'm actually missing here.

This is my type script file:

import { Component, OnInit, ChangeDetectorRef } from '@angular/core';
import { BugService } from '../service/bug.service';
import { Bug } from '../model/bug';
import { NgbModal, NgbActiveModal } from '@ng-bootstrap/ng-bootstrap';
import { BugDetailComponent } from '../../bug-detail/bug-detail.component';

@Component({
   selector: 'bug-list',
   templateUrl: './bug-list.component.html',
   styleUrls: ['./bug-list.component.css']
})

export class BugListComponent implements OnInit {

  private bugs: Bug[] = [];

  constructor(private bugService: BugService, private cdRef: ChangeDetectorRef, private modalService: NgbModal) { }

  ngOnInit() {
    this.getAddedBugs();
  }

  getAddedBugs() {
    this.bugService.getAddedBugs().subscribe(bug => {
        this.bugs.push(bug);
        this.cdRef.detectChanges();
    },
        err => {
            console.error("unable to get added bug - ", err);
        });
  }

  open() {
     const modalRef = this.modalService.open(BugDetailComponent);
     modalRef.componentInstance.name = 'World';
  }
}

I import BugDetailComponent which I then reference inside the open() function. When I click close after the modal has appeared that's when I see the error message.

My HTML is as follows:

<div class="modal-header" [id]="modalId">
<button type="button" class="close" aria-label="Close" (click)="activeModal.dismiss('Cross click')">
    <span aria-hidden="true">&times;</span>
  </button>
<h4 class="modal-title">Hi there!</h4>
</div>
<div class="modal-body">
  <p>Hello, {{name}}!</p>
</div>
<div class="modal-footer">
   <button type="button" class="btn btn-secondary" (click)="activeModal.close('Close click')">Close</button>
</div>

Could someone please shed some light into why I receive this error and maybe help me fix it?

If anyone is having the same issue (i tried the solution by Code Ratchet, but ran into the same issue as Adrita Sharma).

const modalRef = this.modalService.open(BugDetailComponent);

I was able to use close and dismiss by using modalRef.close() in the template.

example:

<button type="button" class="btn btn-secondary" (click)="modalRef.close('Close click')">Close</button>

you can add in your file app.module.ts : the providers: [ NgbActiveModal ],

Solution 3:^[3]

Add NgbActiveModal in providers[NgbActiveModal] of your module.it will avaiable in all your component of your module then declare its variable in constructor function of your componet like constructor(private ngvActiveModal: NgbActiveModal);

Solution 4:^[4]

You can run into same error in case import "NgbModal" is missing in line

import { NgbModal, NgbActiveModal } from '@ng-bootstrap/ng-bootstrap';
