XNAT download_dir called in a slicer module does not work as expected on fetching some of images, while exactly the same code works fine when run outside slicer

Hello,

In one module I’d developed functionality to connect to RIA database through XNAT api and download specific images to local. Unfortunately I learned that for some unknown reason to me it drops on download_dir. I tried a lot to find the issue and after a lot investigations I know that the same exact code that I’m running in slicer works perfectly if I run it outside slicer.
the code is as simple as:

import xnat
username=#username
password=#password
ria = xnat.connect('http://ria.ds.umcutrecht.nl/', user=username, password=password)
...
try:
   scan.resources["DICOM"].download_dir(temp_download_dir+"\\")
except:
   print("could not download!")

basically the error is something that I never get running the code outside slicer, something like this:

    scan.resources["DICOM"].download_dir(
  File "C:\Users\saeed\AppData\Local\NA-MIC\Slicer 5.0.2\lib\Python\Lib\site-packages\xnat\mixin.py", line 591, in download_dir
    zip_file.extractall(target_dir)
  File "C:\Users\saeed\AppData\Local\NA-MIC\Slicer 5.0.2\lib\Python\Lib\zipfile.py", line 1633, in extractall
    self._extract_member(zipinfo, path, pwd)
  File "C:\Users\saeed\AppData\Local\NA-MIC\Slicer 5.0.2\lib\Python\Lib\zipfile.py", line 1687, in _extract_member
    open(targetpath, "wb") as target:
FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\saeed\\Desktop\\tmp2\\00-ria\\02-026\\02-026_212596038910566_662398200_20210301\\302\\DICOM\\temp\\02-026_212596038910566_662398200_20210301\\scans\\302-MPR_SAG_3D_PD_SPAIR\\resources\\DICOM\\files\\1.3.46.670589.50.2.15757877403410526784.31298281802920234632-302-43-687f92.dcm'

I was wondering is there any thoughts why this is happening?

Best,
