SlideViewer throws TrackingIdentifier error due to upstream dcmjs bug

[nr59684]

🐛 Bug Report

Affected Repository

This issue affects slim-viewer when using the latest dcmjs release.

Reproduction Steps

1. Draw one or more ROIs in the Slim viewer (each gets a generated roi.uid).
2. Click on Save ROI in SlideViewer which calls handleReportGeneration()
3. Observe console error:

Uncaught Error: Option 'trackingIdentifier' must include a human readable tracking identifier and a tracking unique identifier.

This is caused by a bug in the dcmjs module (see dcmjs-org/dcmjs#434), where TrackingIdentifier’s constructor calls super(options) and erroneously pushes the raw options object into the internal content sequence.

Impact

• All ROI measurement exports from slim-viewer will fail.
• Automated report‐generation workflows break until the upstream fix is released.

Workarounds

1. Wait for upstream merge
   The fix has been submitted in dcmjs-org/dcmjs#434 and is pending review & merge. Once released in a patch for dcmjs, updating your dependency will resolve the error automatically.

2. Use our temporary fix branch
   You can point your project at the following branch to unblock development immediately:

   npm install git+https://github.com/nr59684/dcmjs/tree/fix/trackingidentifier-super-call
