This error indicates that there is a problem with the condition check of a subtree of a leaf node in a hierarchical structure, which is often used for mapping keys in data processing.
  Cause:
  
  Invalid Key Mapping: The error may occur if there is an invalid or inconsistent key mapping defined for the hierarchical structure. This could be due to missing or incorrect entries in the mapping tables.
  Data Integrity Issues: If the data integrity is compromised, such as having orphaned nodes or incorrect parent-child relationships in the hierarchy, it can lead to this error.
  Configuration Issues: Incorrect configuration settings in the system related to the hierarchical data structure or key mapping can also trigger this error.
  Subtree Structure: The specific subtree being referenced may not exist or may not be properly defined, leading to issues when the system attempts to check conditions on it.
  
  Solution:
  
  Check Key Mapping Configuration: Review the key mapping configuration in the system. Ensure that all necessary mappings are correctly defined and that there are no missing entries.
  Validate Hierarchical Structure: Examine the hierarchical structure for any inconsistencies. Ensure that all nodes are correctly linked and that there are no orphaned nodes.
  Data Consistency Check: Run data consistency checks to identify and resolve any integrity issues within the data. This may involve correcting relationships or re-establishing missing links.
  Review Custom Logic: If there is any custom logic implemented for key mapping or hierarchical checks, review it for potential errors or misconfigurations.
