I have a simple flow in RM that reads in data from a repository and then sets the role for one variable - 'operation' to be label. It works fine in RM 5.3.015, but when I execute it on RapidAnalytics (1.2) I get an error at the 'Set Role' operator. In the console it appears like this: com.rapidminer.operator.UserError: The attribute '' does not exist.
It only appears to affect the Set Role operator (this flow is stripped down from a larger flow that worked OK apart from Set Role). It affects all attributes, not just the one in the flow.
I checked the XML and the 'Set Role' operator does appear to be correct (i.e. the attribute name is included)
please always keep Studio and Server on the same minor version (e.g. Studio 6.1 requires Server 2.1). Otherwise you might get weird behavior or broken stuff. In your case the parameter for the attribute got renamed between minor version 2 and 3, so running a 5.3 process on a 1.2 server will result in the server looking for a different parameter than your process contains. If you update RA to 1.3.15, it will work as expected.
