I'm using the Immich app from TrueNAS, how do I properly update it? Or is it being taken care off by TrueNAS?

Edit: I asked on the TrueNAS discord for help and someone who already updated their Immich figured out how to fix the installation afterwards. I copy&paste the guide here:

This guide assumes that Heavyscript is installed and pgAdmin.
https://github.com/Heavybullets8/heavy_script
https://truecharts.org/charts/stable/pgadmin/

• Upgrade Immich to v.1.95.1.

• If Immich fails to deploy check the logs heavyscript pod --logs immich. If the logs complain that indexes need to be deleted continue with this guide.

• Access the shell for the postgres pod heavyscript pod -s immich.

• Select the postgres pod.

• Inside the pod run env and record the password. Then type exit to exit the pod.

• Get the DNS address and port for Immich postgres pod. heavyscript dns -a

• Launch pgAdmin and right-click on Servers select Register > Server.

• In the Connection tab put the hostname and port from step 6. The username is immich and use the password from step 3.

• Once connected create a backup by expanding Servers > Immich > Databases and right-click on immich then select Backup.... Follow the prompts to create a backup.

• Right-click on immich and select Query Tool.

• Use the following query to delete your indexes.

    FROM pg_index X JOIN
         pg_class I ON I.oid = X.indexrelid JOIN
         pg_am A ON A.oid = I.relam
    WHERE A.amname = 'vectors';

• Stop Immich with heavyscript heavyscript app --stop immich.

• Once all pods have scaled down start Immich heavyscript app --start immich.

The SQL query will complain about a syntax error but it will work regardless. It just takes some time to redeploy immich.
