Error 500 when fetching source for 1.20.1 mappings (Yarn)

[TNTStudiosn]

Hello!

I’m getting an error when trying to fetch the source for any class in version 1.20.1 using Yarn mappings on Linkie.

❌ Error message: Failed to fetch source: Request failed with status code 500

✅ Steps to reproduce:

1. Go to https://linkie.shedaniel.dev/
2. Select namespace: yarn
3. Select version: 1.20.1
4. Search for a class like PlayerEntity
5. Error appears and source never loads

This does not happen on versions like 1.20.2 or 1.20.3.

Thank you in advance!
