Server won't start on VM, parsing and datapack errors

[aronayd]

Describe the Bug

Hello, first thank you for your work on the modpack !

I have a problem with the serverpack v8 (also tried with v7), when I run bash start.sh on my oracle VM with ubuntu I get normal logs until the server stops at "Couldn't parse data file immersive_aircraft:biplane". I tried to remove the mod but I got the error on other mod instead.

I used a VM with ubuntu and I installed a java version 21. Strangely when I run the serverpack Fear the Nightfall on the same machine, the server runs perfectly.

The start.sh also has created a server.jar file but running it ends to the same errors messages.

Reproduction Steps

1. Run bash start.sh
2. Wait for world generation
3. Stops at "Couldn't parse data file immersive_aircraft:biplane" and others
   ...

Screenshots and Videos

A video of the console if this can help, I will provide the log too
