RT Slicer Plugin

Hello !
I’m running the docker version of 3D-slicer : GitHub - Slicer/SlicerDocker: Build, package, test, and run 3D Slicer and Slicer Extensions in Docker.

I have a problem when i’m trying to export the RT contour . I have also installed all the plugins.

"Failed to export using plugin DicomRtImportExportPluginClass
Traceback (most recent call last):
File “”, line 3, in
File “/home/sliceruser/Slicer/NA-MIC/Extensions-30822/SlicerRT/lib/Slicer-5.0/qt-scripted-modules/DicomRtImportExportPlugin.py”, line 126, in export
message = slicer.modules.dicomrtimportexport.logic().ExportDicomRTStudy(exportablesCollection)
AttributeError: module ‘modules’ has no attribute ‘dicomrtimportexport’ "

How should I approach this ?

SlicerRT may not be properly installed. Do you get any errors on startup? Please see the log.
