Python Edit Variable

KNIME Analytics Platform

When I open the Optimus v.1.4.1, I'm getting the error: “WARN  Python Edit Variable 2:423:306:282 Errors overwriting node settings with flow variables: Unknown variable "PYTHON_NODES_MAX_ROW_COUNT"

How to deal  with this issue?

Cheers,

Hi Olivia,

This sounds like your Python Edit Variable node is expecting a flow variable that has not yet been created. Is it possible that you create the flow variable inside a wrapped metanode? In that case, please make sure to configure the wrapped node output to pass the flow variable to the outer workflow.

Cheers,
Roland
