Request not working in axios?

Question

React

I have a table that should display the information that I will add through the form + axios

const AddTutorial = () => {
  const initialTutorialState = {
    id: null,
    title: "",
    description: "",
    published: false
  };
  const [tutorial, setTutorial] = useState(initialTutorialState);
  const [submitted, setSubmitted] = useState(false);

  const handleInputChange = event => {
    const { name, value } = event.target;
    setTutorial({ ...tutorial, [name]: value });
  };

  const saveTutorial = () => {
    var data = {
      title: tutorial.title,
      description: tutorial.description
    };

    TutorialDataService.create(data)
      .then(response => {
        setTutorial({
          id: response.data.id,
          title: response.data.title,
          description: response.data.description,
          published: response.data.published
        });
        setSubmitted(true);
        console.log(response.data);
      })
      .catch(e => {
        console.log(e);
      });
  };

  const newTutorial = () => {
    setTutorial(initialTutorialState);
    setSubmitted(false);
  };

Here is the connection to axios >

import axios from "axios";

export default axios.create({
  baseURL: "http://localhost:8080/api",
  headers: {
    "Content-type": "application/json"
  }
});

But it throws an error when trying to add data
