Row level secuirty


I am getting this error when trying to apply the RLS
’ Dataset rules contain only metadata: UserName and/or GroupName. You need to add at least one data column to the dataset’
Data comes directly from Snowflake.
I have another RLS data set as a direct query from Snowflake and it works ok.
Does anyone know what could be the issue?
Cheers, A.

The issue was that I had a column called ‘Groupname’ where I had rls identifiers.
