I am unable to reproduce this. Could you perhaps try the same workflow on one of the standard datasets (zoo, iris, heart-disease) and see if it still fails? Perhaps attach a screenshot so that we know how to get the error.
Hi! As guessed by Marko in #5918, the error was caused by corrupted data: the culprit is among Feature Constructor, Select Columns, Select Rows (with purge) and Edit Domain. I was not able to locate the origin of the corruption (my bad!) or reproduce it with a clean workflow, so I'll close this thread.
What's wrong?
How can we reproduce the problem?
It happens in the Group By widget GUI on a field on which I used a Select Rows widget, when I try to change the default behavior, which is 'Concatenate' checked and everything else unchecked. Here, I picked "mouse" and "rat" and thus discarded "human" and "pogona". I tried using Purge Domain on my flow first, but the error kept showing up.
What's your environment?
