RichApi.Error: GeneralException still occurs when call insertFileFromBase64 in document 'Viewing' mode

[NataliaKravcheniaTR]

When document is in 'Viewing' mode, insertFileFromBase64 throws GeneralException exception

Your Environment

Platform [PC desktop, Mac, iOS, Office on the web]: PC desktop, Mac, Office on the web Host [Excel, Word, PowerPoint, etc.]: Word Browser (if using Office on the web): Chrome

Expected behavior

When document is in 'Viewing' mode, insertFileFromBase64 throws ReadOnlyException (that we can identify that document is read-only) instead of GeneralException exception

Current behavior

When document is in 'Viewing' mode, insertFileFromBase64 throws GeneralException exception

Steps to reproduce

1. Open document in 'Viewing' mode
2. Call await context.document.insertFileFromBase64(base64, "Replace");

Office.context.document.mode always returns 'readWrite' Document.getActiveViewAsync is not working in Word.

Possible solution (Extracted from existing issue, might be incorrect; please verify carefully)

Solution 1:

FYI it looks like this was related to my version of Word. After updating to 2304 I no longer get the error.

  Solution 2:

  If style count passes the limit, Word simply does not gracefully handle the scenario - you end up in a world of undefined behavior. The user should avoid this. We will let you know if Word side improves the experience.

Hi @NataliaKravcheniaTR ,

The viewing mode means that we can only read the file but not edit the file. Any inserted operation not been allowed no matter from human manually or add-in inserted. All the inserting operation from addin will throw exception not only "insertfilefrombase64". Thank you.

[NataliaKravcheniaTR]

Yes, I understand that, but can it be more specific exception instead of GeneralException? Or could we check that document is in 'Viewing' mode? I've tried Office.context.document.mode but it returns readWrite' when a document is in Viewing or Editing mode
