nvda does not automatically read messages received on skype for business

[fernando-jose-silva]

Steps to reproduce:

I'm sure I've seen this working for some time.
I have not used skype for business for a long time but in my current work I'm making use of it again, and when I received a message on skype for business, nvda did not automatically read the received message.
Open a conversation on skype for business type something and wait inside the conversation for your partner to respond.

Actual behavior:

The nvda is mute.

Expected behavior:

Nvda should automatically announce the response received.

I have just reproduced the issue here with NVDA 2020.4 and Skype for business 2016 (16.0.5095.1000).

Technical details

When a new message occurs in the conversation, the following error appears in the log and the message is not vocalized:

ERROR - eventHandler.executeEvent (14:58:49.118) - MainThread (13480):
error executing event: liveRegionChange on <appModules.lync.NetUIRicherLabel object at 0x00A49150> with extra args of {}

If I put the navigation object (and the focus) on the last message and open the log, I get the following dev info:

Looking at the comments in lync.py appModule that manages this application, it is clear that it was not expected that the object containing the message have a value set to None.
Probably it was different in a previous version of Skype for business / Lync.
