document.body.clear() fails with exceptions on Word Online Script Lab about office-js

something with the content of this document is what makes it fail. we are investigating the issue. sorry for the insane delay!

Have narrowed down the steps to reproduce this issue. It only happens when the document body has only one single paragraph which contains the unsupported features such as field and/or unsupported content controls. This is a bug, and we are working on a fix.

However, the above script actually fails at the step when you try to insert content control to the range which is the inserted base64 stream that contains a field. It fails because field is not supported in Word Online, and therefore we disallow insert content control on the range.

I had the similar trouble. The following code worked for me:
Word.run(async (context) => { let range = context.document.getSelection(); let pageRange = range.parentBody.getRange(); pageRange.delete(); await context.sync(); })
