based on what am seeing here, it seems the ways you are exporting your module is the one giving you problem.

Instead of module.exports, you wrote mosule.export

category:{
        category:String,
        required:[true,"Please Enter Product Category"],
    }

if you want an array of catagory then you can use this

category:{
        type: Array,
        required:[true,"Please Enter Product Category"],
    }
