Failed to load DICOM SEG series using dicom study json

Bug Report

Describe the Bug

When loading a study via the Study Dicom Json and the study contains a series and its segmentation (DICOM SEG), the viewer fails to load the segmentation series:

error messages:

• ToolbarRow: Cannot read properties of undefined (reading ‘SeriesInstanceUID’)
• Referenced series for SEG dataset not present.
• Source data not present

Interestingly, the exact same series load correctly together when using the viewer /local route:

Running OHIF Viewer 4.12.18 from the docker hub. Also just tested in 4.12.19 local dev branch.

What steps can we follow to reproduce the bug?

1. Have a set of a dicom image and a dicom-seg segmentation made using e.g. dcmqi (DICOM for Quantitative Imaging) library
2. Have a dicom json containing two series 1) original dicom image and 2) dicom segmentation
3. Load the dicom json using the route /viewer?url=<json_url>

After fixing the ReferencedSeriesSequence, now it’s failing because it misses another SQ metadata, PerFrameFunctionalGroupsSequence. I find it inconvenient to having to serialize these data into the dicom json, when the OHIF can actually correctly parse them by itself. Is it possible to let OHIF fetch these missing metadata directly from the dicom files?

you can activate the OHIFDicomTagBrowserExtension https://github.com/OHIF/Viewers/blob/master/platform/viewer/src/index.js#L57 for your local build, and you can explore the DICOM structure. I hope it helps.
