It is possible to set as Section child a TextRun without using a Paragraph

[sentientmachin3]

I don't think this is an issue, but I find it useful to highlight it in case someone else encounters this behaviour. Accidentally I passed as Section child a TextRun instead of a paragraph:

this.doc = new Document({
      sections: [
        {
          children: [new TextRun({ text: 'Hello world' })],
        },
      ],
    })

The compiler did not complain about it, so I tried it and the document was just a blank page. According to the documentation and the type definition we are supposed to pass (Paragraph | Table | TableOfContents)[] as children.
Passing a Paragraph did solve the "issue".

Versions: TS 4.7.2, library version 7.4.1

I don't know why the compiler does not complain, any explanations?

Not possible sorry,

Every TextRun needs to be in a paragraph

Unfortunately, thats simply how Word works
