Fix the Fabric API Missing Dependency Error
What to check when Minecraft says Fabric API is missing, outdated, or incompatible with a Fabric mod.
A missing dependency error usually means a mod expects Fabric API but the jar is not present, is disabled, or targets the wrong Minecraft version. The fix is often simple: download the matching Fabric API jar and place it in the same mods folder as the mod.
If the error says Fabric API is too old, keep the Minecraft version the same and choose a newer Fabric API build for that version. If the error says the file is for another Minecraft version, replace it with a build that matches your launcher profile.
Check the launcher profile
Make sure you are launching the Fabric profile, not the vanilla profile. Fabric API will not load in a normal vanilla Minecraft profile because the Fabric Loader is what reads the mods folder.
Check duplicate jars
Remove duplicate Fabric API jars if your folder has several versions at the same time. Keeping one clean, matching jar is easier to troubleshoot than leaving old files in the folder.
