This error typically arises when the system is unable to find the necessary shadow mapping for the specified DataSource and release version.
  Cause:
  
  Missing Shadow Mapping: The shadow mapping for the DataSource has not been created or is missing. This can happen if the DataSource was recently created or modified, and the corresponding shadow mapping was not generated.
