I saw some Github issues related to this failure :

• https://github.com/vitest-dev/vitest/issues/4391

• https://github.com/vitest-dev/vitest/issues/4567

• https://github.com/rollup/rollup/issues/5199

but none of them was working.

Even if Node 22.13.0 is compatible with Angular 20 (https://angular.dev/reference/versions#actively-supported-versions), the failure was fixed by using a newer version of Node : v24.2.0
