Unable to get property 'getElementsByTagName' of undefined or null reference
Steps to reproduce:
- Embed widget with chat & feedback on a page
- At least 1 agent goes online
- Chat tab becomes visible
- Click chat tab
Chat window opens
Console error says "SCRIPT5007: Unable to get property 'getElementsByTagName' of undefined or null reference" in file widget-1.4.gz.js"
Upon cursory inspection it appears that there is a content_template for the chat widget that is not actually added to the DOM. This causes the error above once the chat tab tries to actually load the chat interface.
