Group by node with "CATEGORIA WAZE" not in spec error

[jmancero]

A “group by” node is getting an error (see attachment). When entering the node, one column is highlighted (see attachment).

Any idea on why this is happening?

Hi @jmancero.
Wellcome.

The previous structure of table has changed.
That fields was droped. Just move it to the left.
