Encountered a Java exception for sample process 24_FPGrowth

I encountered a Java exception error while running the sample process 24_FPGrowth. I have attached the process picture showing the location (the only modification I did was adding the Retrieve Data another time and connected it to output port to see the raw data). Also, the error is attached.

Hello @amitdeokar,

Are you able to import the process as XML and send it to us, so that we can try reproducing the error you are getting? This way we can try checking if there is something under the bonnet that is not working.

From the RapidMiner Studio GUI go to View->Show Panel->XML

The XML panel will show up. You can then select the XML and copy so it can be shared with others. You can also paste XML directly into the panel. To make it import, you have to press the validate button (a small, green tick mark at the top left of the XML panel).

All the best,

Rodrigo.

Interestingly, after running it a couple of times, the error did not appear again. Not sure what the issue was, but I can't replicate it right now. If I encounter it again, I will send the process XML.
