Import image failed

[davidhdh]

Guys

We aim to use the Python client API to interact with Cytomine and mainly the import image function.
Using the provided python import image file, we 've faced some error for which we are not able to troubleshoot

The command line executed is the followinng:

python3 upload_image.py --cytomine_host http://core.pdee4.local --cytomine_upload_host http://upload.pdee4.local --cytomine_public_key some_login --cytomine_private_key some_pwd --filepath some_image_file

On the client side we've received this import error

[2021-09-27 15:41:06,831][INFO] [GET] [currentuser] CURRENT USER - 337 : dvo-test | 200 OK
[2021-09-27 15:41:06,848][INFO] [GET] [storage collection] 1 objects | 200 OK
[2021-09-27 15:41:07,478][ERROR] Error during image upload.
False

Looking at the backend server log , we do have an null pointer exception raised during the processing of the request
Below the part of the processing log .

May I ask you to explain us how we could troubleshoot this kind of error ?
So far we are still not able to spot the root cause of this error.

Many Thanks
