How to mock axios.get() with mockRejectedValue

Question

I have a function which does

      axios
      .get(//URL)
      .then((response) => {
        return res.json({ /*build response*/ });
      })
      .catch(function (error) {
         return res.status(500).json({ status: error.response.status, error: error.response.data });
      }

I am trying to mock the error object in the test

  it("returns 500", async () => {
    axios.get.mockRejectedValue(new Error({ response: { 
    status: 500, data: "Internal Server Error" }}));
    const resp = await request(app).get("/");
    //expect ....

});

This is not working for me, I get thrown: "Exceeded timeout of 5000 ms for a test.. What I am missing here?

It works when I mock a positive response

     axios.get.mockResolvedValue({ mockResponse });
