I don't understand why my axios.get(firebase project / .json) file not working properly. What am I doing wrong here, any idea???

import axios from "axios";
class allClass extends Component {
  state = {
    item: [],
    data: [],
    loaded: false,
  };
  componentDidMount() {
    axios
      .get("https://foodie-ghar-default-rtdb.firebaseio.com/.json")
      .then((data) => {
        this.setState({ data: data.data, loaded: true });
      })
      .catch((err) => console.log("Some Error"))
      .then(console.log("Lets try this "));
  }
