Problems with proxmox-backup-client command and crontab

[Meister177]

Hi,
currently I'm trying to run the backups via crontab.

I'll keep the examples as small as possible, therefore I explain my problem using the proxmox-backup-client list command.

When I run the command in the CLI directly (logged in as root on my Proxmox server), everything is working as intended.

proxmox-backup-client list --repository 'user@pbs!Token@IPv4:Datastore'

Then I created two files.

1. .pbs.env containing

   1. PBS_REPOSITORY=user@pbs!Token@IPv4:Datastore
      PBS_PASSWORD=secret

2. pbs-test.sh containing

   1. #!/bin/bash
      
      source /root/.pbs.env
      
      proxmox-backup-client list --repository "$PBS_REPOSITORY"

When I run the script directly in the CLI it still works but as soon as I run it via cron or via

env -i /root/pbs-test.sh

it does not work and I get the error message

Error: error building client for repository user@pbs!TockenName@IPv4: DatastoreName - API token secret must be provided!

I already read many threads here but nothing seems to work. I may miss something obvious here but I just can't see it.

Does anyone has an idea what I'm doing wrong?

Thank you very much

source can't be used in crontab, it's not a Proxmox VE thing.
