Problem Running Query

Hey, i am just finishing my training and want to run a simple query in Explorer.

The query chooses a class - a relationship and a rule.

I get the following error and need a bit of help to guide me as to where to start looking :slight_smile:

thanks, Andrea

Hi Andrea,
I have some questions:

  1. Are you using the data model you built in our training?
  2. What was the query you built?
  3. Did you have reasoning turned on?
