The dummy operator Windowing for Training (2) (replacing series:windowing) cannot be executed.

Hii..

I tried time series forecasting process.

I need to display the chart result from studio version to webservice.

I didn't find any error in my rapidminer studio version, however in rapidminer server i faced this issues. 

 

de.rapidanalytics.ejb.service.ServiceDataSourceException: Error executing process /home/admin/processess/Property for service Property: The dummy operator Windowing for Training (2) (replacing series:windowing) cannot be executed.

 

So i read somewhere, it's about extensions, and i already install series forecasting but the issues remain the same.

 

Please help.

 

Thank you.

@reza_anra92 I'm assuming you are executing this process on a RapidMiner Server? If yes, then you need to install the extensions on the Server as well.
