1. INTERNAL_ERROR - Raised in case of non-specific OS internal failure. 
2. NOT_IMPLEMENTED - Raised when the OS does not support this operation.
3. INVALID_INPUT - Raised when an invalid input parameter is provided (e.g., invalid filter syntax).
4. COMM_FAILURE - Raised when communication to an entity (needed to help fulfill the request) is lost.
