I have a solution running on DW 9.10.13.
I have noticed very often an error (the one from the title) on specific queries without any expressions defined.
But now, all of a sudden, I get this error regardless of the Query I am trying to open. And it seems to be a User-specific error.
I have 2 issues here:
1. Why is this error happening even for correct queries?
2. Can we get a friendlier message for this type of error avoiding breaking the access to all other queries?
This is the complete stack trace:
Group expressions with no expressions are not supported.
