Bug: Is the mod incompatible with Fabric mixin?

[FurryR]

Inertia Utility Mod version: 3.1.3 Minecraft version: 1.16.5 Operating system: Windows 11 (22H2, OS Build 22621.963) Optifine/Other mods: None! Launcher: Hello Minecraft! Launcher

What's the bug: The mod 'inertia' contains invalid entries in its mod json

Crash-report(if applicable)(located in .minecraft/latest.log): Didn't crash

Final checklist:

• [x] I know how to properly use check boxes.
• [x] I have tried to reproduce this bug after removing all other mods, including Optifine or Sodium.
• [x] I have attemped to reproduce this bug using the latest available release of Inertia.

Critical log:

...
[**:**:**] [ForkJoinPool-1-worker-2/WARN]: The mod "inertia" contains invalid entries in its mod json:
- Unsupported root entry "side" at line 7 column 9
- Unsupported root entry "initializers" at line 18 column 17
...

Didn't crash, but I can't load Inertia.

(Probably) solution (fabric.mod.json patch):

{
  "schemaVersion": 1,
  "id": "inertia",
  "name": "Inertia Client",
  "description": "The most advanced utility mod for minecraft.",
  "version": "1.16.5",
  "environment": "client",
  "icon": "assets/minecraft/textures/inertia/logos/squareredicon.png",
  "contact": {

    "issues": "https://github.com/THEREALWWEFAN231/Inertia/issues"
  },
  "authors": [

  ],
  "entrypoints": {
    "client": [
      "inertia.VLWZ"
    ]
  },
  "custom": {
    "mm:early_risers": [
      "inertia.VLWZ"
    ]
  },
  "jars": [
    {
      "file": "META-INF/jars/Fabric-ASM-v2.0.1.jar"
    }
  ]
}

I'm not sure if this one will work.

Crashed after patching fabric.mod.json. Is this utility mod incompatible with Fabric mixin? I do not know a lot on this.

I loaded some optimization mods before, but I have disabled them before installing Inertia. Here is a disabled mod list:

entityculling-fabric-mc1.16.5-1.5.2
fabric-api-0.42.0+1.16
iris-mc1.16.5-1.4.5
lithium-fabric-mc1.16.5-0.6.6
smoothboot-fabric-1.16.5-1.6.0
sodium-fabric-mc1.16.5-0.2.0+build.4

The problem happened after I install these mods, and persists even if I disabled them. If this is my fault (or Mixin will not be supported, etc.), I will close this issue.
