Method "Astronomy/execute" not found in meteor

Okay, I build Game DB schema using astronomy package in meteor.

Then I try to add method to it by extending it in server. (server/gamehandle.js)

import {Game} from '../imports/db/game'
import {DDP} from 'meteor/ddp-client'

Game.extend({
  meteorMethods: {
    AddNewGame(judul){
      const invocation = DDP._CurrentInvocation.get()
      this.namaGame = judul
      this.creator = invocation.userId
      this.createdAt = new Date()
      return this.save()
    }
  }
})

But when I try to run the method in app client using callMethod it throw an error that astronomy/execute not found 404. This the component using it

import {Game} from '../../../db/game'

export function NewGameList(props){
  const { isOpen, onOpen, onClose } = useDisclosure()
  const [judul, setJudul] = useState('')
  const [hasil, setHasil] = useState(null)
  const judulChange = (e) => setJudul(e.target.value)
  const AddGame = new Game()
  
  const handleSubmit = (e) => {
    e.preventDefault()
    AddGame.callMethod('AddNewGame', judul, (err, result) => {
      result ? setHasil(result) : setHasil(err.message) 
      console.log(err)
    })
  }
...

So enlight me, what thing I do wrong?

Finally found the solution from meteor slack. Just need to imports my db file to main js file in server.
