This question is underspecified. Please provide the full JSON for a proper response. I will go out on a limb here and say that one of these answers is correct:
 1. This Prisma was upgraded to XA30 enhanced DICOM, and you are using a version of dcm2niix that pre-dates XA30. If this is the case, you can resolve this by upgrading dcm2niix
  https://github.com/rordenlab/dcm2niix/releases
 2. This is a dataset from a VE11 Prisma where an anonymization tool corrupted or removed key DICOM tags like the CSA header. If this is the case, check the provenance of your data and convert a copy prior to conversion.
 3. You only get this error for derived data, not the raw data. Your MRI console only needs to save raw data, not the derived data as you can derive better derived data after offline processing.

The JSON header will disambiguate these options:
