Error uploading files on Google Cloud

Hi there,
I have just bought and setup eDocman on my domain madein.nc
I have also activated the Google Drive Plugin and set a Client OAuth.
I could connect the plugin to my Google Drive API.
When I upload a file, I get an error :
"Registration failed with the following error: Joomla\Filesystem\File::upload: Failed to move file."
And no document is created.
But I can see the physical file uploaded in my Google Drive.
This is true with a single upload (via Create a new document) or via Batch Upload.
Any advice ?

Hi Stephan,
Please submit a ticket under the Edocman category and provide your site information as well as a super admin account. This will allow me to check and help you resolve the issue related to the Edocman Google Drive plugin.
Thank you very much.
Best regards,
