Description
Hello,
I am trying to run MonaiLabel segmentation on a CT scan, but I encountered this error.

Server logs seems fine as there are no errors here.

Could this be a dicom header issue?

Start by reproducing MONAI Label segmentation on the reported CT scan and inspect the client-side stack trace shown in the screenshots, comparing it with the server logs and DICOM metadata. Done means identifying whether the failure is caused by the DICOM header or another undefined value and documenting a reproducible fix or diagnostic conclusion.
