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名义上的文本operator before theProcess documents from Dataoperator.
