Hello,
I am trying to use html2docx for a react project. But for some reason it keeps crashing with the error:
TypeError: Cannot read properties of undefined (reading 'type')

I have tried it with the example and then changed it. Both codes yield the same error.

var html = `<html lang="en">
                      <head>
                        <meta charset="UTF-8" />
                        <title>Document</title>
                      </head>
                    <body>` +
                    data +
                    `
                    </body>
                  </html>`;
 HTMLtoDOCX(data, null, {
                    table: { row: { cantSplit: true } },
                    footer: true,
                    pageNumber: true,
                  })
                    .then((fileBuffer) => {
                      fs.writeFile("./document.docx", fileBuffer, (error) => {
                        if (error) {
                          console.log("Docx file creation failed");
                          return;
                        }
                        console.log("Docx file created successfully");
                      });
                    })
                    .catch((err) => {
                      alert(err);
               });

This is my rendition of the code.

My enviroment:

macOS: 12.0 Beta
package version: 1.2.4
node version: v16.3.0

Could you possibly post the html string you used? looks like either a bug or an edge case

Apologies for replying so late.

This is my html string.
<h2>Hello, World!</h2><p>This is some text over here.</p>

Edit:
I also have tested this on Windows and got the same error.

@zees98 No worries, Its quite unlikely that the package failed with that html string because I am able to generate it without any issue on my laptop with react-example in the examples/ in this repo.

Could you please let me know what's the end result after clone this repository, and run the example and try it out? I am super curious about this issue.

html-to-docx.docx

Hello again.
So I tried the example and the error I was facing is gone. I also took some assistance from one of your closed issues since my use case is with ReactJS as well.
But now I am receiving another error.
Unhandled Rejection (TypeError): Cannot call a class as a function

My HTML string:

<!DOCTYPE html><html lang="en">
                      <head>
                        <meta charset="UTF-8" />
                        <title>Document</title>
                      </head>
                    <body><h2>Hello World!</h2>
                    </body>
                  </html>

The altered method:

import HTMLtoDOCX from 'html-to-docx';
import { save } from 'file-save'

const html2DocConverter = async () => {
    var html = `<!DOCTYPE html><html lang="en">
                      <head>
                        <meta charset="UTF-8" />
                        <title>Document</title>
                      </head>
                    <body>` +
      text +
      `
                    </body>
                  </html>`;
    console.log(html);
    const fileBuffer = await HTMLtoDOCX(html, null, {
      table: { row: { cantSplit: true } },
      footer: true,
      pageNumber: true,
    });
    await save(fileBuffer, 'trial.docx');
  }

Oh just noticed that the same issue was reported in #92 , hence closing the issue to track it there.

@zees98 I might possibly have figured out the issue, please follow the step in the other issue.
