Hi @tmiotto, @WilliamsL,
There is a known issue for which a fix is coming so that it doesn't happen again.
For your corrupted topic, there is a way to troubleshoot it: you actually need to go to the topic record in Dataverse and fix the record by editing the YAML.
First, navigate to this URL:
[DATAVERSE_URL]/main.aspx?pagetype=entitylist&etn=botcomponent
To get the [DATAVERSE_URL]
- Go to the Overview page of your chatbot
- Click on the solution name - this will open Power Apps
- From Power Apps, click the Settings icon and select Advanced settings.
Then use the search to find the corrupted topic:
Enter the record, and copy the content of the Obi Data (data) field:
Copy the content of the Obi Data field in a text editor or better, VS Code.
The issue is that the YAML has empty expressions.
So, you must find those and remove them.
It's important you leave the indentation intact in YAML.
For example, I had an empty title: (you may also have empty text:)
I fixed it by removing it:
Now copy the fixed full YAML back into the Obi Data (data) field and save.
Back in Power Virtual Agents, your topic should work again:
