BUS-23 Sending out a message using HITL module causes client's chat dialog to be deleted (botpress/botpress botpress/v12#1055)

I have a fairly basic botpress installation running 12.10.2 on windows server. I went through almost all of the production checklist stuff to launch a sample bot for one of my clients to review so I’ve completed:

• Connect to Postgres
• Enabled SSL
• Setup local LANG and DUCKLING servers
• enabled HITL and Misunderstood modules

I am using a simple webchat widget (from the tutorial) and my bot was setup using the example “Small Talk” example bot. There is only a single flow (for misunderstood messages) and the rest of the bot responses were built using the QnA module.

My problem is with HITL. No matter how I try and use the bot, via webchat, via the “emulator” built into the admin site, or using “open chat” from the botpress dashboard… whenever I (as an admin) type a response to a user using HITL I get the following on the user/web visitor’s chat window:

• I get a red notification number next to the profile picture showing “1” to note that the user received a reply from the system
• The entire chat dialog area goes blank - the area where the messages are displayed. In HTML, it’s this section >>

<div class="bpw-msg-list-container">
    <div tabindex="0" class="bpw-msg-list">
         <div></div>
    </div>
</div>

If I, as a user, start talking to the bot again then everything works fine and I still get the standard bot responses as expected using the QnA module. The bpw-msg-list div gets populated with all the back and forth messages between the user and the bot.

But if I try and respond to the user using the HITL module, all divs within bpw-msg-list get deleted and the dialog goes blank again. I don’t see any errors on either the server OR the browser console and have tried on multiple OS and browser combinations.

Any help would be much appreciated!
