RapidMiner Server - Merge Attributes Error
I am running a process that includes the 'Merge Attributes' operator which runs fine in Studio but causes the following error when run on the server:
Error in executed process
The 'Merge Attributes' operator in the process executed by 'Execute impact' failed with: The dummy operator Merge Attributes (replacing operator_toolbox:merge) cannot be executed.
Process (Process) subprocess 'Main Process' ==> +- Execute impact (Execute Process)
This error needs to be fixed before the current process can run.
