Zipline Crafting Fix for Version 1.2.1+1.21.8 (Fabric)

This data pack fixes a critical bug in the Zipline mod (version 1.2.1+1.21.8 for Fabric) that prevents the core Zipline item from being crafted.

The Problem:

A syntax error in the mod's original recipe file (data/zipline/recipes/zipline.json) caused the crafting recipe to be invalid. Specifically, the "key" object incorrectly used the full item component notation (e.g., {"item": "minecraft:gold_ingot"}) which is not supported for simple ingredient definitions in the current version.

The Solution:

This pack replaces the faulty recipe with a corrected one that uses the standard, simple ingredient format (e.g., "minecraft:gold_ingot"). The fixed recipe JSON is included below for verification.

Important Note:

This is a temporary, community-made fix. I have submitted a Pull Request (PR) to the official mod developer. If the main mod has been updated to a version that includes this fix, this data pack will no longer be necessary and can be safely removed.

Installation:

To apply the fix, place this data pack ZIP file into the datapacks folder of your specific Minecraft world save, whether in single-player or on a server. A reload or restart is required.
