Provide angular query in spec file

When I provideQueryClient(() => new QueryClient()) in a spec file for jest testa I get random errors that say cannot read properties of undefined reading

However if I remove the Provider then I get nullInjector error

Maybe try provideAngularQuery instead?

await TestBed.configureTestingModule({
  imports: [MyComponent],
  providers: [
    provideAngularQuery(new QueryClient()),
  ],
}).compileComponents();

await TestBed.configureTestingModule({
  imports: [MyComponent],
  providers: [
    provideAngularQuery(new QueryClient()),
  ],
}).compileComponents();

However, both this and provideQueryClient(() => new QueryClient()) work for me, so it may be something completely different.

I don't know what the random errors are exactly without more information. But recently I got TypeScript errors on queries in Jest unit tests in a NX monorepo which were resolved by removing preserveSymlinks: true from tsconfig.spec.json
