Build error: "don't know how to insertURL /assets/undefined"

[simonihmig]

After re-enabling embroider test scenarios in ember-bootstrap, I am getting this error in CI, also when adding the embroider dependencies locally to this PR (which could serve as a reproduction).

It has worked before, so this seems like a regression.

I debugged this a bit in node:

1. the error is thrown in @embroider/webpack here

2. in the previous step of the call stack, the match for assets/dummy.js seems pretty broken:
   

3. Same when looking at stats.entrypoints map for assets/dummy.js (same for assets/tests.js):
   

Haven't investigated any further. Any idea?

I think this is due to a wrong webpack version, see #791 and #792

Those are fixed on master but not yet released, I need to do a patch release soon.

[NullVoxPopuli]

confirm: I got this error yesterday in an addon and made it go away by manually adding webpack @v5 to my package.json

[simonihmig]

Those are fixed on master but not yet released, I need to do a patch release soon.

I could refer to the master branch of test-setup as an interim solution, but wonder if there is anything left blocking that release? (other than your personal time of course) Anything I/we can do?

Ran into the same thing with @embroider/test-setup (0.40.0)! Turns out that webpack@4 is coming from ember-auto-import, btw.

I'm experiencing this issue as well. I tried yarn add webpack -D and now my tests seem to just hang and throw errors like not ok 1 Chrome 90.0 - [undefined ms] - Global error: Uncaught ReferenceError: Ember is not defined at http://localhost:7357/assets/vendor.js, line 1027

[ef4]

The main thing blocking release is that changes in (I think) ember-cli-babel have left a large swath of embroider's test suite falling.

Seeing the same issue with ember-page-title. Tried with auto-import v2 and get the same result as well. But an older version of auto-import might have been used since some deps don't use v2.

When using resolutions and setting auto-import to v2, I get this:

Cannot find module 'webpack'

Looks like #792 will fix this. Any ideas when this will be released?

[knownasilya]

0.41.0 fixes it for me with auto-import v1 in ember-page-title

[simonihmig]

Confirm. Fixed in 0.41.0!

Anyone know why tests would be hanging for embroider with errors like this?

not ok 1 Chrome 90.0 - [undefined ms] - Global error: Uncaught ReferenceError: Ember is not defined at http://localhost:7357/assets/vendor.js, line 1027
    ---
        browser log: |
            {"type":"error","text":"Uncaught ReferenceError: Ember is not defined at http://localhost:7357/assets/vendor.js, line 1027\n","testContext":{}}
    ...
not ok 2 Chrome 90.0 - [undefined ms] - Global error: Uncaught Error: Could not find module `velocity` imported from `(require)` at http://localhost:7357/assets/vendor.js, line 256

They run for hours and never time out, so I cancel them, and then I see these types of errors. See this PR RobbieTheWagner/ember-shepherd#779

[knownasilya]

@rwwagner90 sounds like you need to use skipBabel setting for velocity maybe? #677 (comment)

[RobbieTheWagner]

@knownasilya I tried that in RobbieTheWagner/ember-shepherd#779 and it still seems to hang with the same error. @ef4 any ideas here?
