Cannot move a node to itself

Error message

Cannot move a node to itself

What it means

A cycle guard in moveNode: when moving nodeId under a non-null parentId, the first check rejects the degenerate case where the node would become its own parent (nodeId === parentId). It fires when a move request designates the node itself as the new parent folder.

Solutions

1. Choose a different destination folder.
2. Guard the move operation against identical source and target.

When it happens

Trigger: Thrown by moveNode when nodeId equals parentId, i.e. a drag-and-drop or move operation targets the node itself as its new parent.

Common situations: Happens when a user drags a folder onto itself in the organize tree. Drop the node onto a different destination folder.
