Could not find module with webpack alias AND gts

[gossi]

My original issue is in #1752 - which I then found out are two issues. So I'm extracting the latter into this one, for which I do have a repro.

When using webpack alias, this works... well until the alias points to an index.gts file. If it is an index.ts file that exports a gts file, then this is the original bug in #1752

The repro is available here: https://github.com/gossi/repro-ember-webpack-alias

Points of interest are:

• ember-cli-build.js - contains alias config
• tsconfig.json - the same config for TS
• The breaking point

When importing a gts file from a location under a webpack alias, this doesn't work. Toggling the import statement in the last link would "fix" it.

The error message is unfortunately not very helpful, yet it describes the phenomena:

The cause for this?

Well, the original issue in bug #1752 was embroider resolver's meta is not propagating - and I think it may has to do something with propagation here. Ie. propagating all babel plugins to entries within the alias config?

This could be something that #1794 intends to try to fix 🤔 the PR is not yet ready to test to see if it fixes your issue but I imagine it will once it's finished
