  Solution:
  To resolve this error, you should:
  
  Review the DMEE Tree Structure: Ensure that you are only adding segment groups or segments under the segment group node. Check the hierarchy of your DMEE tree.
  Correct Node Types: If you have mistakenly added a node that is not a segment or segment group, remove it from the segment group and place it in the appropriate location in the tree.
  Use the Correct Node Types: When creating new nodes, ensure you are selecting the correct type (segment or segment group) that is allowed under the parent node.
