I'm Using react version 18.1.0 and @zarconontol/enzyme-adapter-react-18 for enzyme configs.

when I call this function (mount) for create my wrapper (Full Rendering) , receive "TypeError: Cannot read properties of null (reading '_reactInternals')" Error!

const wrapper = mount(<App />);

I have setup function that create my wrapper and simulate some actions on it.

const setup = (state = {}) => {
  const wrapper = mount(<App />);
  // add value to input box :
  const inputBox = findByTestAttr(wrapper, "input-box");
  inputBox.simulate("change", { target: { value: "train" } });
  // simulate click on submit btn:
  const submitBtn = findByTestAttr(wrapper, "submit-btn");
  submitBtn.simulate("click", { preventDefault() {} });
  return wrapper;
};

So the question is how do I fix this error?

Thanks for your tips :)
