Specifically, the error message states that a node (represented by &1) is not part of any reference needed to build the hierarchical structure. This typically occurs in the context of OData services when there is a mismatch or misconfiguration in the entity relationships.

  Incorrect Entity Set Configuration: The entity set may not be correctly configured to include the node, or the node may not be properly linked to its parent entity.
  
  
  Model Definition Issues: There may be issues in the way the OData model is defined, such as missing associations or incorrect cardinality settings.
  
  
  Service Metadata Issues: The service metadata might not be correctly generated or might be out of sync with the underlying data model.

  Regenerate Service Metadata: If you have made changes to the data model or the OData service, regenerate the service metadata. This can often resolve issues related to outdated or incorrect metadata.
  
  
  Check for Errors in the Service Implementation: If you have custom logic in your OData service implementation, check for any errors or inconsistencies that might be causing the issue.
