process documents error the example set must contain at least one text attribute

Dolar

Hi,

I am new to Rapidminer. I am getting an error that tells the example set must contain at least one text attribute. 



But, I set those as text attribute in Set Role operator:



By the way, there was no type 'Text' at the Import Configuration Wizard:



RapidMiner version: 9.8.001 
OS: Windows 10

Hi @Dolar,

I think you need to add a Nominal to Text operator before the Process documents from Data operator.
