prometheus-paperless-ngx-exporter.service: Unable to locate executable

[Janos66]

Hi,
I have tried several times to install prometheus-paperless-ngx-exporter on Proxmox 9.1.2, but no matter which setup option I use, I either get a script error or with the Advanced Setup option the installation completes, but the service does not start.

Here's what I've done
proxmox shell
bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/prometheus-paperless-ngx-exporter.sh)"

# vi /etc/systemd/system/prometheus-paperless-ngx-exporter.service 
--paperless_url=http://172.21.21.5:8000

# vi /etc/prometheus-paperless-ngx-exporter/paperless_auth_token_file 
SECRET_AUTH_TOKEN xyzblabla123

reboot

Service does not start

journalctl -f

edit:
I've made some progress, I've adjusted the path in the service file.
The correct path is "/usr/bin/prometheus-paperless-exporter"
Now I'm getting this error message.

edit2:
Never mind, it's sorted now.
Knowing that the Paperless-ngx Secret Key is not the API key makes it easier ;)
