Fails to publish to modrinth

[IThundxr]

Using forgix here but the error doesnt sit right with me since that fabric.mod.json still exists in their, asked modrinth support and they told me to report it here

* What went wrong:
Execution failed for task ':publishModrinth'.
> A failure occurred while executing me.modmuss50.mpp.platforms.modrinth.Modrinth$UploadWorkAction
   > Request failed, status: 400 message: Error with multipart data: No fabric.mod.json present for Fabric file.

   forgix {
    group = maven_group
    mergedJarName = "${archives_base_name}-${mod_version}+mc${minecraft_version}.jar"
    outputDir = "build/libs/Merged"

    fabric {
        projectName = "fabric"
        jarLocation = "build/libs/${archives_base_name}-${mod_version}.jar"
    }

    custom {
        projectName = "neoforge"
        jarLocation = "build/libs/${archives_base_name}-${mod_version}.jar"
    }
}
