Unable to start BCG+ 2.3.0 Missing necronomicon 1.0.1

[Lobstram]

Hi!

I just upgraded my server from 2.2.0 to 2.3.0, but it won't start and gives the following error:

mc-1  | [04:10:06] [main/ERROR]: Incompatible mods found!
mc-1  | net.fabricmc.loader.impl.FormattedException: Some of your mods are incompatible with the game or each other!
mc-1  | A potential solution has been determined, this may resolve your problem:

I am running my server via Docker Compose:

Have you confirmed that https://www.curseforge.com/minecraft/mc-mods/necronomicon/files/5091307 is in your modlist? Server files aren't publicly available yet so something might've gone wrong during the installation phase.

I'm not sure what that means within the context of the Docker image that I'm using: https://docker-minecraft-server.readthedocs.io/en/latest/types-and-platforms/mod-platforms/auto-curseforge/ I've always just let it do its thing and haven't touched a single file myself.

I tried starting a brand new server, but got the same error on startup.

I was able to resolve it by downloading Necronomicon-Fabric-1.4.2.jar from the link that you provided and putting it into my mods folder, but I'm not sure if that's the most appropriate way to fix it?

If you're missing a mod, what you did is the proper way to fix it, however, it's odd only missing one mod, but if you're not running into issues between the server and client then you're going to go!
