LoadPluginError: Could not load plugin about nx HOT 10 CLOSED

Hi there 👋 - so this is a bit more complex than one may imagine. Most typically getting this error during a unit test is a result of a test doing something that is causing the project graph to be created. You'll need to mock the project graph during these tests, and while that sounds rough its also going to give you much more accurate and repeatable tests.

Without mocking the graph, the tests will be running generators which create the project graph of the current Nx workspace and make some decisions about that. That's almost always not really what you want. We just recently fixed that behavior on the Nx repo.

This suddenly became a problem for some folks because several of our published generators do rely on the graph now.

You can see how we are mocking this in our unit test setup: https://github.com/nrwl/nx/blob/master/scripts/unit-test-setup.js

Having the same issue. Tests run well on local Mac, but does not work on Linux env in CI.

experiencing the same but with the applicationGenerator from '@nx/next' on v18.3.4

I'm experiencing the same problem. Tests work on MacOS but not on our Linux CI.

It happens when I call the libraryGenerator function from @nx/nest@18.3.4 on a Jest test

from nx.

I have a similar issue with a Jest test also using the libraryGenerator. However, I see the error on both Github Actions / nx agents as well as on my Mac developer machine.

I also tried to copy paste the test in this issue and run the test, and it fails on my mac running Sonoma 14.4.1

from nx.

I got my test to run by following a workaround from mswjs/msw#1851

Object.defineProperties(globalThis, {
  performance: { value: performance, writable: true },
});

Not quite sure why it works, but my test runs again with this 'fix'.

I'm having the same issue when wrapping the service schematic from @schematics/angular, and executing that.

Although, when running locally (MacOS) I get this error

ReferenceError: TextDecoder is not defined

but on CI I get the same as OP.

facing the same issue, but only in the TeamCity environment.
