I am using pdf maker in my StencilJs app using the official Documentation at https://pdfmake.github.io/docs/0.1/getting-started/client-side/ First of all, I have installed it via npm using:

npm install pdfmake

Then I have created the following to test the functionality:

import * as pdfMake from 'pdfmake/build/pdfmake';
import * as pdfFonts from 'pdfmake/build/vfs_fonts';


(<any>pdfMake).vfs = pdfFonts.pdfMake.vfs; 

export class PDFCreateService {


  constructor() {
 // empty
 }


public createNachrichtPDF(message: string): any {
 const fileName: string = 'ba-postfach-' + moment(new Date()).format('DD-MM-YYYY');

  const docDefinition = {
    content: [message]
  };


  return pdfMake.createPdf(docDefinition);
}

}

This code does not work and in the class My-Messages where I instantiate this class, I keep on getting the following error:

index-2022e853.js:2706 TypeError: Cannot read properties of undefined 
(reading 'pdfMake') at my-messages.entry.js:78239 undefined

Uncaught (in promise) Error: Constructor for "my-messages#undefined" was 
not found at initializeComponent

How can I solve this error?
