Error running process on RapidMiner Server

Hi! I was executing my project in RapidMiner Server when I found this issue:

The process contains one or more 'Dummy' operators: Operator 'Lag Series (39)' (replacing 'series:lag_series'), Operator 'Lag Series (40)' (replacing 'series:lag_series'), Operator 'Lag Series (41)' (replacing 'series:lag_series'), Operator 'Lag Series (42)' (replacing 'series:lag_series'), Operator 'Lag Series (29)' (replacing 'series:lag_series'), Operator 'Lag Series (30)' (replacing 'series:lag_series'), Operator 'Lag Series (37)' (replacing 'series:lag_series'), Operator 'Lag Series (38)' (replacing 'series:lag_series'), Operator 'Lag Series (25)' (replacing 'series:lag_series'), Operator 'Lag Series (26)' (replacing 'series:lag_series'), Operator 'Lag Series (27)' (replacing 'series:lag_series'), Operator 'Lag Series (28)' (replacing 'series:lag_series'), Operator 'Lag Series (35)' (replacing 'series:lag_series'), Operator 'Lag Series (36)' (replacing 'series:lag_series'), Operator 'Lag Series (33)' (replacing 'series:lag_series'), Operator 'Lag Series (34)' (replacing 'series:lag_series'), Operator 'Lag Series (31)' (replacing 'series:lag_series'), Operator 'Lag Series (32)' (replacing 'series:lag_series'), Operator 'Lag Series (23)' (replacing 'series:lag_series'), Operator 'Lag Series (24)' (replacing 'series:lag_series'), Operator 'Lag Series (15)' (replacing 'series:lag_series'), Operator 'Lag Series (22)' (replacing 'series:lag_series'), Operator 'Lag Series (8)' (replacing 'series:lag_series'), Operator 'Lag Series (14)' (replacing 'series:lag_series'), Operator 'Lag Series (12)' (replacing 'series:lag_series'), Operator 'Lag Series (13)' (replacing 'series:lag_series'), Operator 'Lag Series (5)' (replacing 'series:lag_series'), Operator 'Lag Series (11)' (replacing 'series:lag_series'), Operator 'Lag Series (6)' (replacing 'series:lag_series'), Operator 'Lag Series (7)' (replacing 'series:lag_series'), Operator 'Lag Series (9)' (replacing 'series:lag_series'), Operator 'Lag Series (10)' (replacing 'series:lag_series'), Operator 'Lag Series (16)' (replacing 'series:lag_series'), Operator 'Lag Series (17)' (replacing 'series:lag_series'), Operator 'Lag Series (20)' (replacing 'series:lag_series'), Operator 'Lag Series (21)' (replacing 'series:lag_series'), Operator 'Lag Series (18)' (replacing 'series:lag_series'), Operator 'Lag Series (19)' (replacing 'series:lag_series'), Operator 'Lag Series' (replacing 'series:lag_series'), Operator 'Lag Series (2)' (replacing 'series:lag_series'), Operator 'Lag Series (3)' (replacing 'series:lag_series'), Operator 'Lag Series (4)' (replacing 'series:lag_series'). Please make sure all required extensions are installed on RapidMiner Server and re-submit the process.


I have been looking for in the last link that i attach but when i install the missing plugins in my server, the problem remains the same. Also I have tried to synchronize the Server and Studio versions. The idea was that the updates installed in one of them were in the other too. This has not worked either, so I guess it's not an update issue.


If someone knows how to solve it, I would appreciate it.

Thank you so much

Hi,

the "Lag Series" operator is from the old Value Series extension; which seems not be be installed on the server.

You can replace it with the newer "Lag" operator, which is part of RapidMiner now and as such automatically also present in Server and Studio as well.

Best,
David
