Have you tried the forums for ARM?

At first sight this appears to be an application issue rather than a TrueNAS one.

Do you have a MakeMKV license for ripping Blurays?

See Configuring ARM · automatic-ripping-machine/automatic-ripping-machine Wiki · GitHub

Apparently makemkv is still in beta and licenses are still free - see MakeMKV is free while in beta - www.makemkv.com (Since this expires in a week, there may be an updated license posted soon.)

If you have a license key but the TrueNAS App settings pages have nowhere for you to enter it, that that would be a TrueNAS issue - otherwise you need to get support from the ARM application support folks.

sorry i didnt have the licience installed, i have deleted and recreated the app several times. Re-adding the key, the main error still persists. i wanted to check here as there is a truenas guide (custom app) on there site and they specifically say they dont support truenas issues. i will head over there an see if they can help me.

on there wiki:
…/wiki/Alternate-Install-TrueNAS

right at the top of the page:
This installation method is not supported or maintained by the ARM Developers. For full support and continued maintenance, we recommend installing ARM via the supported [Docker Container](LINK OMITTED). This installation method was developed for those that wish to use ARM without Docker.

*Use at your own risk

so we will see what support i do recieve… if i find a solution i will post it here

issue fixed, just by chance!
i converted the app to a custom app,
still didnt work, but after converting the truenas “update available” flag appeared, edited the custom app changing the docker tag to latest.
after re-deploying the app this issue is resolved. im guessing the version that the “official” app uses needs to be updated to a newer release.

I suspect that this note relates to TrueNAS 24.04 or earlier which used Kubernetes.

Now that TrueNAS uses Docker, I suspect that this does NOT apply. But you would need to check with the ARM support team.
