  Solution:
  
  Check Data Consistency: Ensure that the data being processed is consistent and adheres to the expected formats and structures. Validate the entries in the cluster table to ensure there are no anomalies.
  Review Migration Settings: If this error occurs during a migration process, review the settings and configurations of the migration tool being used. Ensure that the correct mapping and transformation rules are applied.
