    </table>
  </div>
  <button (click)="print()">PDF</button>



  <button type="button" class="btn btn-primary" data-toggle="modal" data-target=".bd-example-modal-lg">Large modal</button>

  <div class="modal fade bd-example-modal-lg" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="true">
    <div class="modal-dialog modal-lg">
      <div class="modal-content">
        <button (click)="print()">Export To PDF</button>


        <div class="pdf-container">
          <pdf-viewer [src]="src"
                      [original-size]="false"
          ></pdf-viewer>
        </div>



      </div>
    </div>
  </div>

My Ts part is

import { analyzeAndValidateNgModules } from '@angular/compiler';
import { Component, OnInit } from '@angular/core';
import { ViewChild, ElementRef } from '@angular/core';
//import {jsPDF} from 'jspdf';
declare var jsPDF: any;
@Component({
  selector: 'app-pdf-generator',
  templateUrl: './pdf-generator.component.html',
  styleUrls: ['./pdf-generator.component.css']
})
export class PdfGeneratorComponent implements OnInit {

  constructor() { }

  ngOnInit(): void {
  }

  name = 'Angular';

  @ViewChild('content', {static: false}) content: ElementRef;


  title = 'exports-pdf';
  @ViewChild('exports') exports: ElementRef;

  public print(): void {
    const doc = new jsPDF('p', 'pt', 'letter');

    const content = this.exports.nativeElement;

    const margins = {
      top: 80,
      bottom: 60,
      left: 40,
      width: 522
    };
    console.log(doc);
      doc.fromHTML(content.innerHTML, margins.left, margins.top, {}, function () {
      //  doc.output('export.pdf'); ** REMOVE **
        doc.save("export.pdf");
      }, margins);
  }

    
    src = "https://vadimdez.github.io/ng2-pdf-viewer/assets/pdf-test.pdf";
  }

My error is
