Solid Query: "mutate" is not a function when testing

Hello everyone. I have a page component Post.page.tsx that uses createQuery and createMutation. When I try to test that component, the error says TypeError: mutate is not a function. I have a test utils that's basically a wrapper of render from @solidjs/testing-library. The only place where I call mutate function in that page component is in onDeletePost function in Post.vm.tsx file which is used inside of Post.page.tsx, but only called when some button clicked. I'm not sure why the error says like so, even if I'm not even clicked anything in my test case. here is the repo: https://github.com/rifandani/solid-app
