globalTeardown works locally but fails on Kubernetes workload

Question

I'm trying to run a simple jest setup on kubernetes. Until now it works fine on my local workstation (WLS2 on WIN10).

PROBLEM: When I add a globalTeardown to my package.json, the function fails in my kubernetes workload, but works when executed locally. Both of the runs are invoked by npm run test

The log of the kubernetes workload prints this error:

[...] // Tests are executed as usual

  ]
}

I have no idea how this can be connected to Powershell, as the used image is based in Ubuntu. Could it be an caused by using Rancher Desktop integrated to WSL2?

./tests/customTeardown.js

export default async function () {
    console.log("Done");
};

Update:

I found this not to happen, when using Kind instead of Rancher Desktop. So this seems to be an integration issue of Rancher Desktop.
