Getting error after integrating pdfnet-node library in angular.

I was trying to integrate the data extraction module with my Angular project. And I am getting an error in the console. Which I feel I am getting because of the @pdftron/pdfnet-node library. Can someone check this.

import { AfterViewInit, Component, ElementRef, EventEmitter, OnInit, Output, ViewChild } from '@angular/core';
import WebViewer, { Core, WebViewerInstance } from "@pdftron/webviewer";
import *  as PDFNetNode from '@pdftron/pdfnet-node';
import { Subject } from "rxjs";

@Component({
    selector: 'app-root',
    styleUrls: ['app.component.css'],
    templateUrl: '
        <div class="page">
          <div class="header">Data Extraction Module Integration For Form Fields</div>
          <div #viewer class="viewer"></div>
        </div>
    '
})
export class AppComponent implements AfterViewInit {
    wvInstance?: WebViewerInstance;

    @ViewChild('viewer') viewer!: ElementRef;

    @Output() coreControlsEvent: EventEmitter<string> = new EventEmitter();

    private documentLoaded$: Subject<void>;

    constructor() {
        this.documentLoaded$ = new Subject<void>();
    }

    ngAfterViewInit(): void {

        WebViewer({
            path: '../lib',
            initialDoc: '../files/form-for-changes-in-pan.pdf',
            licenseKey: 'YOUR COMMERCIAL LICENSE KEY',
            fullAPI: true
        }, this.viewer.nativeElement).then(instance => {
            this.wvInstance = instance;

            this.coreControlsEvent.emit(instance.UI.LayoutMode.Continuous);

            const { documentViewer, Annotations, annotationManager, PDFNet } = instance.Core;
            PDFNet.initialize(YOUR COMMERCIAL LICENSE KEY, 'ems')

            documentViewer.addEventListener('documentLoaded', async () => {
                this.documentLoaded$.next();

                if (await PDFNetNode.PDFNet.DataExtractionModule.isModuleAvailable(PDFNetNode.PDFNet.DataExtractionModule.DataExtractionEngine.e_Form)) {
                    const json = await PDFNetNode.PDFNet.DataExtractionModule.extractDataAsString('../files/form-for-changes-in-pan.pdf', PDFNetNode.PDFNet.DataExtractionModule.DataExtractionEngine.e_Form);
                    console.log(json)
                }

            });
        })
    }
}

And I am getting this error in the console

I am also providing code snippet of package.json for better understanding.

If this is not the right way to integrate the data extraction module for detecting form fields in a pdf, then please let me know the correct way.
