The hou.Node API has various methods for wiring and un-wiring inputs and outputs in the network. If you try to wire an object into a node input that is not a node or is not allowed to be wired to that input, Houdini will raise this exception.
Note that Houdini does allow certain wiring operations you might expect to fail (such as looping a node’s output back into its own input) but then immediately flags them as errors in the network editor.
