Paperless-NGX LXC document_import not availible

[treffNIX9815]

Hello,

I am trying to move my Paperless instance from Home Assistant to a standalone instance. I read some instructions on how to do this.
Paperless has a function, document_exporter, to export documents with metadata, and the function document_importer to import.
I installed the Paperless-ngx LXC with PVE helper scripts, and then I used the document_importer function, but I get an error:

root@paperless-ngx:/# document_importer
-bash: document_importer: command not found

Could you please implement this function as well?
Thanks!
