Hello, I can't figure out what's the problem:

  "schemaVersion": 1,
  "id": "gemsrealm",
  "version": "${version}",
  "name": "Gems Realm",
  "description": "Ultimate Gems & Metals Compat Mod",
  "authors": [

    ]
  },

    "moonlight": ">=1.20-2.13.50",
    "everycomp": ">=1.20-2.7.19"

}

and here's the crash-log

I appreciate the help.

Can i get explanation for what's the problem?

Ok I compared your post to the original file. i see the link for "homepage" and "sources" are different. i'll run a quick test. Will close this if it's resolved. otherwise, will report back.

I've tried with the code you provided. and it doesn't work.

EDIT: Take a look at the log

FINAL UPDATE:
Turned out the config is corrupted. i had to delete the config folder. The project is copied from another project. just Renamed the modID and folder name.
