Describe the bug
DEPLOY_TRUENAS_APIKEY, DEPLOY_TRUENAS_HOSTNAME, DEPLOY_TRUENAS_PROTOCOL are set to undefined config value acme_truenasws_apikey, acme_truenasws_hostname, acme_truenasws_protocol.

To Reproduce
Steps to reproduce the behavior:

1. Go to Services - ACME Client - Automations
2. Click on "Automations" tab
3. Create or edit an automation, choose "Update certificate to TrueNAS Server (Websocket API)" on Run Command
4. Enter the API key, hostname and scheme
5. Add this automation to a certificate setting, manually run the automation
6. See the automation failed with error "TrueNAS API key not found, please set the DEPLOY_TRUENAS_APIKEY environment variable."

Expected behavior
The console shows "Environment variables: OK" when the acme script truenas_ws.sh gets correct variables.
