This error indicates that there is a problem with the delta index for InfoObjects in the specified namespace, which can affect data extraction and reporting.
  Cause:
  
  Delta Index Issues: The delta index may be inconsistent or corrupted. This can happen due to various reasons, such as failed data loads, inconsistencies in the data model, or issues during the extraction process.
