I am trying to create a module to export a docx using the npm docx package. However each time I run it I get the following error (even though the import is there). I checked for circular imports as well but can’t identify any:

TypeError: docx_1.HeadingLevel is undefined

My code is as follows:

import { HeadingLevel, Document, Packer, Paragraph, TextRun, ImageRun } from 'docx';

const downloadObjectAsDocx = (exportObj: any, exportName: string) => {
// Function to generate the document
  console.log(exportObj);


  // Create document
  const doc = new Document({
    sections: [
      {
        properties: {},
        children: [
          // Title
          new Paragraph({
            text: exportObj.applicationInfo ? exportObj.applicationInfo.name : '',
            heading: HeadingLevel.TITLE,
          }),
          // Description Header
          new Paragraph({
            text: 'Description',
            heading: HeadingLevel.HEADING_1,
          }),
          // Description Content
          new Paragraph({
            children: [
              new TextRun({
                text: exportObj?.applicationInfo?.description || '',
                break: 1,
              }),
            ],
          }),
          // Architecture Header
          new Paragraph({
            text: 'Architecture',
            heading: HeadingLevel.HEADING_1,
          }),
          // Architecture Image
          new Paragraph({
            children: [
              new ImageRun({
                data: exportObj?.architecture?.image || '', // base64 string from JSON
                transformation: {
                  width: 500,
                  height: 300,
                },
              }),
            ],
          }),
          // Assumptions Header
          new Paragraph({
            text: 'Assumptions',
            heading: HeadingLevel.HEADING_1,
          }),
          // Dynamically added Assumptions

          ...(exportObj.assumptions || []).map((assumption: any) =>
            new Paragraph({
              text: assumption.content,
              bullet: {
                level: 0,
              },
            }),
          ),
        ],
      },
    ],
  });

  // Use Packer to generate a blob and simulate a download
  void Packer.toBlob(doc).then(blob => {
    const url = URL.createObjectURL(blob);
    var downloadAnchorNode = document.createElement('a');
    downloadAnchorNode.setAttribute('href', url);
    downloadAnchorNode.setAttribute('download', exportName + '.docx');
    document.body.appendChild(downloadAnchorNode);
    downloadAnchorNode.click();
    downloadAnchorNode.remove();
  });
};


export default downloadObjectAsDocx;
