NextJS swcMinify is breaking arquero

[victorgdb]

Hello, just to let you know that:

This code

  let array = aq
    .from(data)
    .orderby(aq.desc('value'))
    .derive({
      cumulative: aq.rolling((d) => op.sum(d.value)),
    })
    .derive({
      share_cumulative: (d) => d.cumulative / op.sum(d.value),
    })
    .derive({
      category: (d) => (d.share_cumulative > 0.98 ? 'Other' : d.label),
    })
    .groupby('category')
    .rollup({
      value: (d) => op.sum(d.value),
    })
    .objects();

Produces the following error when minified

To solve the issue I had to update next.config.js to:

const moduleExports = {
  reactStrictMode: true,
  swcMinify: false,
  experimental: {
    externalDir: true,
    typedRoutes: true,
  },

Or simply remove the faulty code.

Impacted versions:

    "arquero": "^5.2.0",
    "next": "^14.0.4",

Thanks! I converted this issue to a discussion post. Other tools may perform code transformations that are not compatible with Arquero. Thank you for documenting one potential fix!
