TileEntity

Make a test without crittersandcompanions

Looks like Almanac Lib is missing - add this mod: https://www.curseforge.com/minecraft/mc-mods/almanac-lib/files/5803518

I have no idea - maybe it is some kind of issue with the Launcher

This is not a forge only server - there is craftbukkit, which is causing this issue

Sounds like the modpack is not loaded on server-side Add the server.log with sites like https://mclo.gs/

Add the new crash-report

I have no idea

Which mod was it?

Does the reforged build work? https://www.curseforge.com/minecraft/mc-mods/copious-dogs-reforged/files/5978379

Yes, but this modpack is adding fabric mods via Sinytra Connector

Does it work without the fabric mods?

Looks like an issue with fabric-api or a fabric mod Try other builds of fabric-api

Try an older build of fabric-api: https://www.curseforge.com/minecraft/mc-mods/fabric-api/files/6321634

Add crash-reports with sites like https://mclo.gs/ Replace Patchouli with this build: https://www.curseforge.com/minecraft/mc-mods/patchouli/files/4966125

Is there a mod Fabric Resource Conditions API? If not, then it refers to fabric-api (try other builds) or a fabric mod - remove these one by one until you find the one causing this issue

Start with adding connector / connector-extras and fabric-api If this works, add the fabric mods one by one or in groups until you find the mod causing this issue

Make a test without fabric-api and all fabric mods

Add the full crash-report or latest.log (logs-folder) with sites like https://mclo.gs/ and paste the link to it here

copiousdogs is not working

Remove dawnera - this mod is not working on a server

You will need fabric loader 0.14.25 or a fork of bclib https://github.com/quiqueck/BCLib/issues/136
