App won't boot, accessing import which doesn't exist, 'ember'

[NullVoxPopuli]

Uncaught ReferenceError: Ember is not defined

This code:

Repro:

• https://github.com/universal-ember/ember-primitives/pull/55
• pnpm i
• pnpm build
• pnpm start
• visit http://localhost:5001

Here is the code to fix: https://github.com/ember-fastboot/ember-cli-fastboot/blob/ddbfeb36c14001c79527f1d1ca64b4f594a1bf91/packages/ember-cli-fastboot/vendor/experimental-render-mode-rehydrate.js#L4

The questions:

• for Ember that no longer provides global Ember, v4+, how should it be referenced?
  • all the AMD stuff is private API
  • Providing "The Ember global" is too much api surface area, because the above code doesn't need access to all that much

i was running into the same error today...

while looking the issues, i have found out, that there exists an other issue which has noted the same lines https://github.com/ember-fastboot/ember-cli-fastboot/issues/924

Just stumbled upon this. I assume this happening only when running under Embroider?

In this case you can workaround this by setting staticEmberSource: false. Then that AMD require stuff should be working again...

Just ran into this as well.

Setting this flag does indeed resolve the issue. I wonder what changes are needed to have support for static Ember source 🤔

+1 to this. Hit this after upgrading from embroider/test-setup v2.x to v4.x.
