Clone is not a function?

[SpyridonZ]

Using basically a modified version of the example in the documentation at the "Dynamic Filter" section here: https://cult-of-coders.github.io/grapher/#Introduction

Regular queries are working, but if I attempt to use clone on any reusable queries, it's not working. Here's my code:

productQuery.js:

import {ProductCollection} from "../db/ProductCollection";

export default ProductCollection.createQuery(
    {
    $filter({filters, options, params}) {
        filters.code = params.code;
    },
    $options: {sort: {code: -1}},
    code: 1,
    price: 1,
    author: 1
});

Usage:

import { check } from 'meteor/check';
import { ProductCollection } from "../db/ProductCollection";
const { DateTime } = require("luxon");
import {Match} from 'meteor/check';
import productQuery from "./productQuery"; // Grapher query instance

Meteor.methods({

    'products.get'() {

        if (!this.userId) {
            throw new Meteor.Error('Access Denied: User not authenticated.');
        }

        // Example query
        return productQuery.clone({
            code: "0000"
        }).fetch()
    },

This results in:

Any ideas how to resolve this error? I tried searching and strangely I can't find anyone else who encountered this issue...

Hi @SpyridonZ, you should provide a reproduction repository to get help on your issue. There is a big chance that this is the result of a misuse of the package.
