Minecraft CurseForge

So i'm trying to create my first modpack but i'm getting troubles with the manifest.json file.
When i try to submit the file, curse reject my project because of this:

References file with invalid status: 3024120 (projectID 400342 - Rejected).

I know this error is because a mod, but cannot tell wich mod, is there a way to search for mods using the ProjectID number?

{
   "projectID": 400342,
   "fileID": 3024120,
   "required": true
},

Hi I just had the exact same message with my modpack, any idea what mod it was? Or we could compare modlists.

In reply to Viogor:

 Optifine, i forgot to remove it (optifine is not allowed in modpacks)

any idea what mod it was? Or we could compare modlists.

In reply to GhostRice23:

 Already did some time ago, but I feel the admins of this website simply don't care about spam. Look at the other subforums, they're filled with spam.
