Answer 1

I was making a different mistake like I have created the Schema but the issue was that I didn't use schema model (for insert, update, read and delete the doc).

i.e. I have created the collection something like that:

const playerSchema = new Schema({
    bowling: {
        style: String,
        arm: String,
    }
})

export const PlayerSchema = model('Player', playerSchema)

but didn't use or call PlayerSchema model somewhere that's why I was getting this error.
