  Solution:
  
  Check Model Definition: Review the definition of the virtual model in the SAP ESH configuration. Ensure that a root node is defined and that it is correctly set up.
  Recreate the Model: If the model is corrupted or improperly configured, consider recreating the virtual model from scratch, ensuring that all necessary components, including the root node, are included.
  Validate Configuration: Go through the configuration settings of the virtual model to ensure that all parameters are set correctly and that there are no missing links or references.
  Check for Updates: Ensure that your SAP system is up to date with the latest patches and updates, as there may be bug fixes related to this issue.
  Consult Documentation: Refer to the official SAP documentation for Enterprise Search and virtual models to ensure that you are following the correct procedures for model creation and configuration.
