  Invalid Data: The data being processed may contain invalid or unexpected values that cannot be converted. This could be due to data quality issues in the source system.
  
  
  Configuration Issues: There may be issues with the configuration of the InfoObjects, transformations, or data sources that lead to incorrect value conversions.
