Cannot read properties of undefined (reading 'getRootNode')

Hi there 👋🏻 ,

I hope it is the right place to ask, and I apologize if not. I'm currently trying to bump version of happy-dom from 2.51.0 to a greater one using vitest & vue 3 but I'm facing the following error:

happy-dom version: 3.1.0 (I've tried multiple version between this one and 2.51.0)
vitest version: 0.10.0

It seems to be related to usage of @headlessui/vue (version 1.5.0) but I haven't found yet the root cause.

Thanks in advance for your help, wish you a nice day ☀️

Thank you for reporting @smarlhens! 🙂

It might be a bug as a change was made on that part of the code in v2.51.1.

I will investigate what may have caused it.

Hey! I'm also running into issues with this using vitest and react with happy-dom 3.1.1 in my case it seems like it might be related to certain components from the mui component library

@WonderPanda you don't happen to have a open project that I can test in? 🙂

I'm facing the same error while using a remix template with vitest. You can check out this repo and run the following to reproduce it:

1. npm i
2. npm run test

It should fail with the following error message:

The test is located in this file.

Somehow it's only possible to run the first test without errors although both tests are identical. I'm also not 100% sure if this a problem with happy-dom testing-library or vitest. But the error messages links the error to happy-dom.

Thanks in advance for any feedback and for your support!!!

Here is a codesandbox with the minimal possible code to produce this error. Indeed, it only happens when running a second test (when adding a .only to the second test, it does not happen).

I can confirm this is related to happy-dom. I changed the vitest environment to jsdom, and all tests passed.
In my case, it also happens when running a second test.

I'm blocked by this as well in happy-dom@6.0.2

I am sorry that it has taken such a long time for me to fix this. It has been a lot going on in my private and work life, but now I will have time to focus on Happy DOM again.

I have made a fix. Hopefully it will solve your problem. Feel free to re-open otherwise.
