UnhandledPromiseRejection error in React test

I am doing test on the React+Typescript using React Testing Library and Jest. This test could not run at all with the following error:

[UnhandledPromiseRejection: This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason “TypeError: Cannot read properties of undefined (reading ‘json’)”.] {
code: ‘ERR_UNHANDLED_REJECTION’
}

Here is my test. Please help my to fix it.

const renderComponent = (): RenderResult => {
  return render(
      <List />,
    {}
  );
};

const { getByTestId, findByTestId, findByText } = screen;

const renderElements = (): any => {
  const component = renderComponent();
  return {
    deleteIcon: screen.getByTestId("delete-icon"),
    dialogPopup: screen.getByTestId("dialog-popup"),
    component,
  };
};

describe("When click on Delete icon", () => {
  it("should show Dialog Confirmation Popup", () => {
    const { deleteIcon, dialogPopup } = renderElements();
    userEvent.click(deleteIcon);
    expect(dialogPopup).toBeInTheDocument();
  });
});
