TypeError: Factory, Object, or Array expected when custom bundling

[twiertzema]

When attempting to pull in only the parts of the library that I need (following the examples from https://mathjs.org/docs/custom_bundling.html), I receive the following error:

Uncaught TypeError: Factory, Object, or Array expected
    at flattenImports (import.js:102)
    at import.js:80
    at Array.forEach (<anonymous>)
    at flattenImports (import.js:80)
    at Object.mathImport [as import] (import.js:108)
    at create (create.js:235)

This is my importing code:

import { create, matrix, multiply } from 'mathjs'
const math = create({ matrix, multiply })

I am using version 6.0.2.

The create function expects factory functions, like matrixDependencies and multiplyDependencies. The docs page you're referring to shows an example: https://mathjs.org/docs/custom_bundling.html
