Not getting the expected output by using TinyMCE in react

I'm storing the TinyMCE editor text in MongoDB using react and node. When I retrieve the data from MongoDB I'm not getting the text as expected. For example:

I text I wrote in TinyMCE is like this:

The output I'm getting is the only simple plain text:

This is the react that I wrote for posting text in MongoDB:

import React, { useState, useRef } from "react";
import { Editor } from '@tinymce/tinymce-react';
import axios from "axios";
const PostBlog = () => {
    const fileInput = useRef(null);
    const [description, setDescription] = useState("");
    const handleSubmit = (event) => {
        event.preventDefault();
        const formData = new FormData();
        formData.append('description',description);
        axios.post('/blog/posts',formData).then((res) => {
            console.log(res.body);
            console.log('successfully posted');
        });
        window.alert("added successfully");
    }
    const editorRef = useRef(null);
    const cleanUp = (input) =>{
        
        const div = document.createElement('div');
        div.innerHTML = input;
        return div.innerText;
    }
    const log = () => {
        if (editorRef.current) {
            const text = cleanUp(editorRef.current.getContent());
            setDescription(text);
            console.log(description);
            window.alert('Description added successfully');
        }
    };
    return (
