importSync error: `Expected identifier but found "*"` when using the `@cached` decorator in `ember-headless-table` with `@embroider/vite`

[johanrd]

@mansona thanks for an exciting demo today during the Ember.js Europe meetup🚀 I tried the steps tonight on my own app, and it turns out I belong to the 40% that wouldn't get vite to run with ember-source 5.7.0:)

Since ember-headless-table is a V2 addon that works well in webpack, I am posting it as an issue here, and not on the addon repo.

Steps to reproduce:

1. Checkout the ember-headless-table-expected-identifier-on-cached-decorator branch in this repository: https://github.com/johanrd/ember-vite-app
2. Run pnpm vite
3. See the following error in the console:

✘ [ERROR] Expected identifier but found "*"

    node_modules/.pnpm/[email protected]_@[email protected]_@[email protected]_@ember+test-waiters@3_iveooflb4fr3ajv754gzshjrpu/node_modules/ember-headless-table/dist/table-443deac1.js:3:18:

  let error = new Error(text);
              ^

}

The compiled V2 output of the addon seems to include an importSync reference to @glimmer/tracking and ember-cached-decorator-polyfill:

let cached = macroCondition(dependencySatisfies('ember-source', '>= 4.1.0-alpha.0')) ? importSync('@glimmer/tracking').cached : importSync('ember-cached-decorator-polyfill').cached;

Perhaps the use of ember-cached-decorator-polyfill is the issue here? not sure. Possibly also related to #1672?

Oh, that's exactly what i saw today as well. A fix is being worked on here https://github.com/ef4/babel-import-util/pull/11
