ERROR: Node ... cannot be dropped because it is attached to one or more child nodes

Reason:

You attempted to drop a node using drop_node() but specified a node that is attached to one or more child nodes.

Resolution:

Ensure you specify the name of a detached node.

Tips:

• Detach the child nodes first, then drop the node.
• Use the star$topology view to find which nodes are attached to the node you want to drop.
