ddns-updater on TrueNAS-Scale ; "permissions - Exited"

[t3r1n4]

When running ddns-updater app within TrueNAS-Scale 25.04.1, registering WAN-IP with CloudFlare API, the app remains in yellow "Deploying" state permanently. The address update does successfully register, but the app status fails transition to green "Running" as expected.

In the "Workloads" section, TrueNAS reports two (2) containers:
ddns - Starting
permissions - Exited

The log file for "permissions - Exited" says the following:
2025-07-03 21:17:32.852472+00:00=== Applying configuration on volume with identifier [data] ===
2025-07-03 21:17:32.852507+00:00Path [/mnt/permission/data] is not empty, skipping...
2025-07-03 21:17:32.852515+00:00Total time taken: 0.18ms

All of the app defaults have been selected ; (eg; userID, groupID 568)

Volume Mounts are as follows:
Type Source Destination
ddns-vol-mounts bind /mnt/.ix-apps/app_mounts/ddns-updater/data /updater/data
permissions-vol-mounts bind /mnt/.ix-apps/app_mounts/ddns-updater/data /mnt/permission/data

Container shells don't seem to respond.
Any ideas as to "why" this is hanging up?

I found a workaround that allows the ddns-updater app to complete "Deploying" and show green status "Running"

Edit the DDNS-Updater app settings;
In the "Additional Environmental Variables" section, click "Add"
set "Name" to RESOLVER_ADDRESS
set "Value" to 1.1.1.1:53
click "Update"

I chose 1.1.1.1 given that my ddns function is using CloudFlare.
But I then found that other values also work! (e.g. 8.8.8.8:53 or 9.9.9.9:53)
I guess it's now mandatory for the app to have this variable provided?
Kinda seems like something that should be done automatically by the app?
