Cannot read property 'exports' of undefined

All our tests pass on multiple macOS machines, and on semaphore-ci, but when we try to build and run tests on a new debian box, we get this error in loader.js:143

not ok 1320 Chrome 72.0 - TestLoader Failures: zipbooks/tests/unit/utils/request-log-test: could not be loaded

We cannot find any information or have any guesses what might be causing this error.

ember-cli: 3.1.4
node: 8.5.0
os: linux x64

This felt like a bug to me since the exact same code works on a different operating system, but let me know if I'm wrong and I'll seek help in a more appropriate place

I am seeing this now too, only when upgrading to the latest Ember Data. With 3.27 it works fine; with 3.28 I get this error.

All of my tests run locally just fine; they fail in CI and in docker. Moreover, if I run them in docker with ember test -s, the Chromium browser that attaches from within the container fails; but I can connect from a browser on the host machine and the tests will load and all pass. I thought perhaps it was the version of Chromium, but I downloaded the same version (albeit for macOS) and it also works correctly from the host machine.

@atomkirk Did you ever discover any workaround?
