How to get attributes for SOPClassUID and SOPInstanceUID with C-FIND?

Using DCMTK, I am doing query with C-FIND to get SOPClassUID and SOPInstanceUID. I need these attributes later to copy SR file with C-MOVE. First I use StudyInstanceUID and PatientID to get SeriesInstanceUID (query at SERIES level with FINDPatientRootQueryRetrieveInformationModel). This is always successful. Then, I use the SeriesInstanceUID plus previous levels unique keys to get the SOPClassUID and SOPInstanceUID (query at IMAGE level with FINDPatientRootQueryRetrieveInformationModel). This is successful in most of the cases but there are some cases that the result is null for both SOPClassUID and SOPInstanceUID with error "Received Final Find Response (Failed: UnableToProcess)". I have attached the logs for the successful and failed cases below. What am I doing wrong? Thank you very much for your help. Logs for the successful case ` Perform a query at SERIES level to get SeriesInstanceUID
