Getting "500 Server Error: Internal Server Error" while running segmentation model in OHIF

Hello Project-MONAI Team,

I have built the OHIF viewer plugin and the Orthanc server by following this link. The OHIF viewer is being connected with the MONAI Label as I can see the MONAI Label app and segmentation model name. But, When I am clicking on the segmentation model run button it is throwing an error. I am sharing the error trace below.

I am not sure if this is from MONAI Label or OHIF viewer or Orthanc server but I guess it may be from the Orthanc server.

Thank you in advance

@aihsani After following the shared instructions, it’s working fine now. However, I have followed the same steps earlier but unfortunately, it didn’t work.

Thank you so much @aihsani @SachidanandAlle and the whole MONAILabel Team for the support.

@kevinpatel13896 have you followed the script in the code box under: https://docs.monai.io/projects/label/en/latest/quickstart.html#ubuntu … We found that there are compatibility issues if the .so files aren’t updated independently.
