[BUG] Issue with DialogEngine using Small Talk template
Describe the bug Sometimes, using a Small Talk template, an error is thrown by the DialogEngine saying that a certain content-element does not exist.
To Reproduce Steps to reproduce the behavior:
- Start a clean install of Botpress
- Create a new bot using the Small Talk template
- Train the bot
- Talk to the bot and sometimes it seems to result in having errors in the DialogEngine (see screenshot)
Note that the test content-element is mentioned nowhere in the bot archive.
Expected behavior There shouldn't be any errors when running a template bot.
Screenshots

Environment (please complete the following information):
- OS: Arch Linux
- Browser Chrome
- Browser Version 98.0.4758.80
- Botpress Version Happened on v12.26.10 (but pretty sure this issue is older than that)
- NodeJS 12.18.1
Additional context Add any other context about the problem here.
@laurentlp Is it really an issue with the dialog engine ? or is it only that the builtin text does not exist ?
@EFF the built-in text did not exist on the disk or even in any of the flows/skills, o I consider this an issue with the dialog engine since it does a lookup for something that seems to have never existed. Also, I cannot seem to be able to consistently reproduce the issue, although we managed to reproduce it more than once.
