One of the many great new features of the PVA Unified Canvas is the ability to create and work with a Fallback topic when no other topics match a user’s query, but did you know that you can still add a Fallback topic to older bots (without using Bot Framework Composer)?
It’s simple. Just perform the following steps:
- Navigate to your bot in Power Virtual Agents web browser
- Select the Cog in the top right of the page
- Select “General settings”
- Go to “System fallback” on left-hand side of modal dialog
- Click “Add”
- Navigate to your new “Fallback” system topic and utilize the “UnrecognizedTriggerPhrase” variable in it to access what the user typed
As always, I hope you enjoyed this post!
Cheers,
