Word - Paragraphs have a uniqueLocalId of null

[ddonushev]

Your Environment

• Platform: PC desktop
• Host: Word
• Office version number: 2308 (Build 16731.20600 Click-to-Run)
• Operating System: Windows 11 E, 10.0.22631

Expected behavior

The uniqueLocalId property of a Word.Paragraph should be a GUID string.

Current behavior

The uniqueLocalId property of a Word.Paragraph is always null.

Steps to reproduce

1. Using the hello-world-example, but practically any add-in where you access a paragraph's unique id would do.
2. Replace the contents of the original sayHello() function lines 27-34 with the following:

Word.run(async (context) => {
  const firstParagraph = context.document.body.paragraphs.getFirst();
  firstParagraph.load("uniqueLocalId");
  await context.sync();
  console.log(firstParagraph.uniqueLocalId);
});

3. Run this in desktop Word as you do: office-addin-debugging start src/manifest.xml desktop.
4. Observe that the uniqueLocalId is null.

Additional details

1. Office.isSetSupported("WordApi", "1.6") returns false, which shouldn't be the case - and it does so for 1.1 too.
2. I cannot reproduce this issue on the web version. Unique IDs are returned as expected there.
3. I could very well be missing something obvious.

Hi @ddonushev, sorry for the late response. I have tried it on my Word desktop and didn't see the issue. My Word version is 17531(an internal version which hasn't been rolled out to Production till now). It seems the newest version on CC production is about 17328, would you please update your office version and have a try?

I have the same issue on build 2308 (which is still used by customers on the semi-annual enterprise channel).

But I am also noticing that onParagraphChanged is not being triggered. This build should support Word API 1.6 and the uniqueLocalId property does exist, it is just always null.
