Word found unreadable content error

[Bogdan0205]

Hello!

I am getting this annoying warning when trying to open a generated docx file.

The document is as simple as it gets (as it was only a test)

new Document({
    sections: [
      {
        children: [
          new Paragraph({
            children: [new TextRun('Hello World')],
          }),
        ],
      },
    ],
  })

This happens even with an empty document, with an empty children array.

Any idea what might be causing it?

Hi @Bogdan0205 , i'm having a similar problem, for me is only occurring on the browser (react app), when i run it with node JS it work fine

For me the error is caused by duplicate numbering definitions in numbering.xml when multiple Document instances are created in the same browser context (e.g., due to React re-renders), for now i'm using Web Worker to avoid this problem.
