OCI-53800
The DICOM object does not contain attribute string.
Cause
The DICOM object did not contain the attribute that was required for conformance validation.
Action
Determine if the locator path is properly constructed. All attributes used in the locator path must be defined in the DICOM standard, and must not be retired. All attributes except the last attribute in the locator path must be of sequence type. If the locator path is correct, verify if the DICOM data dictionary is up to date. If the data dictionary is obsolete, update it using the ORD_DICOM_ADMIN repository API.
