Hi,
let me explain what happend.
In RM we map Nominal values to Integers. So if you store nominals we have a nominal mapping store like:
i -> 0
love ->1
RapidMiner ->2
In your case an operator wants to get the Nominalstring for the mapped value 3. This is not exsisting. To be honest i never experienced this error so far. Can you maybe tell me which operator is throwing the error?

Hey Martin,
thank you so much for your answer.
To be honest i am not sure which operator throws the error. The only operator which throws an alert sign is Generate ID (2). Could this be possible? Or how can I figure out which operator needs to be fixed?
Again, thank you so much for helping a desperate student.

Hello @Mo1 - if you're trying to get someone's attention on the forum, please use the @ handle with the username in your post. It will be more likely to attract that person's attention - particularly someone as busy as @mschmitz
