Set Role Operator - attribute missing in input example set
Newbie
Hello,
New to RapidMiner. I am following the process described in the "Automatic Classification of Documents" tutorial (can't post links yet but it's in RapidMiner Academy). When it gets to the Set Role operator, I get an error message where it says the attribute is missing in the input dataset (Image 1). However when looking at the input ExampleSet, the attribute in question seems to be present (Image 2). Plus, it is present as a choice within the Set Role operator dialog box (Image 3). Also including the full error message (Image 4).
I see a similar question here but I don't understand how to apply it in my case and it is quite old - based on the response if this is a bug it would be supposed to be fixed by now? (again, can't post links but the post is called "Set Role operator returning attribute does not exist [SOLVED]")
See below for screenshots and XML. Thanks in advance for any guidance.
OS: Mac OS Big Sur (11.7.4)
RapidMiner version: 10.1.002
Executing in: RapidMiner Studio
Dataset has 2 attributes, 395 examples.

Hi @creditz
Try bypassing or skipping your Filter Examples operator. It's difficult to be certain without your data, but it looks like you are filtering out all of your data. Make sure you have data going into the Set Role operator. If that doesn't work, see if you can provide a sample of the data you are using.
Best,
