Cannot import from @glimmer/tracking/primitives/cache

[NullVoxPopuli]

Using
@embroider/test-setup 0.47.2
ember-source ~3.28.0
ember-cli-babel ^7.26.6

And this code:

import { getValue } from '@glimmer/tracking/primitives/cache';

I'm getting this error:

Module not found: Error: Can't resolve '@glimmer/tracking/primitives/cache' in '$TMPDIR/embroider/2340f5/node_modules/ember-resources/dist/index.js'
Did you mean 'cache.js'?
BREAKING CHANGE: The request '@glimmer/tracking/primitives/cache' failed to resolve only because it was resolved as fully specified
(probably because the origin is strict EcmaScript Module, e. g. a module with javascript mimetype, a '*.mjs' file, or a '*.js' file where the package.json contains '"type": "module"').
The extension in the request is mandatory for it to be fully specified.
Add the extension to the request.

also occurs on ember-source ~4.0.0
and all versions of webpack 5, it seems

Worth noting that this (failing) import is in a v2 addon (ember-resources)! 👆

I guess this might be related to @glimmer/tracking being a "virtual package"?

I looked and debugged a bit into https://github.com/embroider-build/embroider/blob/master/packages/core/src/babel-plugin-adjust-imports.ts, especially this part. Don't know if that's relevant, unfortunately I was not able to draw any conclusions...

Note that there are even more errors for different packages (see linked CI run above):

Module not found: Error: Can't resolve '../../../../externals/@ember/application' in '$TMPDIR/embroider/2340f5/node_modules/ember-resources/dist'
Did you mean 'application.js'?

there is also this: https://github.com/embroider-build/embroider/blob/master/packages/compat/src/compat-adapters/%40glimmer/tracking.ts#L23

[NullVoxPopuli]

@ef4 are the compat adapters used for v2 addons?
(Or, should they be?)

[ef4]

No, v2 addons don't run through the compat adapters. They exist to help convert v1 to v2.

But if you're asking if a v2 addon that consumes a v1 addon will see the v1 addon after it has gone through a compat adapter, yes, it needs to work that way.

@NullVoxPopuli Can't wait to use ember-resources@4 any longer 😭

[NullVoxPopuli]

I think this is resolved?

@nightire you can use latest ember-resources with embroider now <3

Yes, I can confirm it works now, congrats!
