Bug Description

viafabric-0.4.11+43-dev is tagged as compatible with minecraft 1.20.1 on Modrinth but the fabric.mod.json depends does not includes 1.20.1.
https://modrinth.com/mod/viafabric/versions?g=1.20.1

In case it's merely a mc version tag issue on Modrinth disregard this issue.

After editing fabric.mod.json to accept 1.20.1 the server won't start and I get the error pasted above

Steps to Reproduce

edit viafabric-0.4.11+43-dev's fabric.mod.json to accept minecraft 1.20.1
put viafabric-0.4.11+43-dev and fabric-api-0.90.7+1.20.1 as the only mods in the mod folder
start server

Expected Behavior

server starts

Additional Server Info

using fabric-api-0.90.7+1.20.1

Checklist

• I have checked if this is specific to ViaFabric platform, and doesn't happen when running it on other platforms (Paper/Sponge/Velocity/Waterfall).
• I have included a ViaVersion dump.
• If applicable, I have included a paste (not a screenshot) of the error.
• I have tried the latest build(s) from https://ci.viaversion.com/ and the issue still persists.

Minecraft 1.20.1 isn't supported anymore, you can't just edit the fabric mod json and except the mod to run since Minecraft's code has changed in these versions, use either the ViaProxy or Via As a service.

Update: 1.20.1 is supported as it is now an LTS version. (for now)
