Catch Errors (Var Ports)

KNIME Base Nodes version 4.3.2.v202103021015 by KNIME AG, Zurich, Switzerland

This node forwards the input from the first port if the execution was successful. If execution on the top branch failed (and a matching try node was connected before the failing node!) then the input from the second port will be forwarded and the second variable outport will contain information about the observed error.


Always populate error variables
If selected, the variables will also be generated when the node is not failing with the default values as selected.
Default for FailingNode variable:

Default for FailingNodeMessage variable:
